Um refere-se ao SmCo 1:5 e o outro ao SmCo 2:17. O SmCo 1:5 permite-lhe criar formas intrincadas e complexas. Enquanto o SmCo 2:17 permite-lhe criar formas maiores. Como este \u00e9 altamente fr\u00e1gil e n\u00e3o \u00e9 bom na forma\u00e7\u00e3o de formas complexas. Saiba mais sobre estes tipos nas sec\u00e7\u00f5es seguintes:<\/p>\n<h4>1. SmCo 1:5<\/h4>\n<p>Os \u00edmanes SmCo 1:5 referem-se aos \u00edmanes que cont\u00eam um \u00e1tomo de sam\u00e1rio e cinco \u00e1tomos de cobalto. Este tipo \u00e9 uma varia\u00e7\u00e3o mais antiga dos \u00edmanes de sam\u00e1rio-cobalto. Estes \u00edmanes s\u00e3o comparativamente mais fracos do que os do tipo SmCo 2:17. Mas estes \u00edmanes n\u00e3o s\u00e3o fr\u00e1geis e permitem uma maquina\u00e7\u00e3o f\u00e1cil em componentes complexos e mais pequenos. O SmCo 1:5, devido ao facto de n\u00e3o conter ferro, apresenta uma elevada resist\u00eancia \u00e0 ferrugem. \u00c9 poss\u00edvel trabalhar com estes \u00edmanes at\u00e9 uma temperatura de 250<sup>0<\/sup>C.<\/p>\n<h4>2. SmCo 2:17<\/h4>\n<p>O SmCo 2:17 \u00e9 uma das mais recentes varia\u00e7\u00f5es dos \u00edmanes de sam\u00e1rio-cobalto. A composi\u00e7\u00e3o destes \u00edmanes cont\u00e9m dois \u00e1tomos de sam\u00e1rio e 17 \u00e1tomos de cobalto. \u00c9 poss\u00edvel trabalhar com estes \u00edmanes a temperaturas at\u00e9 3500C. O facto de suportarem temperaturas mais elevadas significa que s\u00e3o adequados para fornos, motores e componentes de m\u00e1quinas. Estes \u00edmanes n\u00e3o apresentam uma perda f\u00e1cil na desmagnetiza\u00e7\u00e3o.

Uma refere-se aos \u00edmanes de Alnico isotr\u00f3picos. A carater\u00edstica deste tipo \u00e9 que pode magnetiz\u00e1-lo da forma ou dire\u00e7\u00e3o que desejar. Por outro lado, os im\u00e3s de alnico anisotr\u00f3picos n\u00e3o permitem magnetiz\u00e1-los em nenhuma dire\u00e7\u00e3o. Pelo contr\u00e1rio, apresentam uma magnetiza\u00e7\u00e3o numa \u00fanica dire\u00e7\u00e3o.<\/p>\n<h4>\u00cdmanes de alnico sinterizados<\/h4>\n<p>O Alnico sinterizado tem um n\u00edvel de magnetismo mais baixo do que os \u00edmanes de Alnico fundido. Permitem-lhe desenvolver formas mais complexas e intrincadas a partir deles. O custo dos \u00edmanes de Alnico sinterizado \u00e9 comparativamente mais baixo. Assim, estes \u00edmanes s\u00e3o os mais adequados para projectos de baixo or\u00e7amento. O Alnico sinterizado pode funcionar de forma not\u00e1vel a temperaturas mais elevadas, como 450<sup>0<\/sup>C ou 840<sup>0<\/sup>F.<\/p>\n<h4>\u00cdmanes de alnico fundidos<\/h4>\n<p>Os \u00edmanes de Alnico fundidos, como o nome indica, formam-se devido \u00e0 t\u00e9cnica de fundi\u00e7\u00e3o. Seguem v\u00e1rios processos de tratamento t\u00e9rmico para terminar a forma\u00e7\u00e3o do \u00edman. O campo magn\u00e9tico dos \u00edmanes de alnico fundido \u00e9 muito mais forte do que o dos \u00edmanes de alnico sinterizado. Quando se compara o custo dos dois, o alnico sinterizado \u00e9 um claro vencedor. Estes \u00edmanes podem suportar temperaturas de cerca de 525<sup>0<\/sup>C at\u00e9 977<sup>0<\/sup>F.<\/p>\n<h4>1. Alnico 2<\/h4>\n<p>Os \u00edmanes de Alnico 2 s\u00e3o \u00edmanes sinterizados ou fundidos dispon\u00edveis em diferentes formas e desenhos. Por exemplo, pode escolher um \u00edman de Alnico 2 fundido em barra para o seu captador de guitarra.<\/p>\n<p>A sua temperatura de funcionamento \u00e9 de cerca de 450\u00b0C. Naturalmente, isto aplica-se tanto aos \u00edmanes de alnico fundidos como aos sinterizados.<\/p>\n<h4>2. Alnico 3<\/h4>\n<p>Tal como o Alnico 2, a temperatura de funcionamento dos \u00edmanes de Alnico 3 \u00e9 de 450\u00b0C. Normalmente, isto \u00e9 comum com os \u00edmanes de Alnico 3 fundidos.<\/p>\n<h4>3. Alnico 5<\/h4>\n<p>Os \u00edmanes de Alnico 5 s\u00e3o mais fortes do que os \u00edmanes de Alnico 2 e os \u00edmanes de Alnico 3. Quando utilizados como captadores de guitarra, produzem um som mais forte e agressivo.<\/p>\n<p>Tal como os tr\u00eas primeiros \u00edmanes, a sua temperatura m\u00e1xima de funcionamento \u00e9 de 450\u00b0C, especialmente para os \u00edmanes sinterizados de Alnico 5.<\/p>\n<p>Por outro lado, os \u00edmanes de Alnico 5 fundidos t\u00eam uma temperatura m\u00e1xima de 525\u00b0C, tal como o Alnico 5DG.<\/p>\n<h4>4. Alnico 6<\/h4>\n<p>Na maioria dos casos, tanto os \u00edmanes de Alnico 6 sinterizados como os fundidos t\u00eam uma temperatura m\u00e1xima de funcionamento de 525\u00b0C.<\/p>\n<h4>5. Alnico 8<\/h4>\n<p>Tanto para os \u00edmanes de Alnico 8 fundidos como para os sinterizados, a temperatura de funcionamento \u00e9 de 555\u00b0C. \u00c9 a temperatura de trabalho mais elevada para os \u00edmanes de Alnico.<\/p>\n<h4>6.

Alguns dos principais aspectos que requerem a sua aten\u00e7\u00e3o s\u00e3o<\/p>\n<h3>Temperatura m\u00e1xima de funcionamento<\/h3>\n<p>A temperatura de funcionamento \u00e9 um aspeto fundamental que requer a sua aten\u00e7\u00e3o no in\u00edcio. \u00c9 essencial determinar o intervalo de temperatura em que vai utilizar o \u00edman. Isto deve-se ao facto de os \u00edmanes possu\u00edrem uma maior sensibilidade \u00e0s flutua\u00e7\u00f5es de temperatura.<\/p>\n<p>Tenha em aten\u00e7\u00e3o que nem todos os tipos de \u00edmanes s\u00e3o adequados para todas as gamas de temperatura. \u00c9 essencial considerar a temperatura de funcionamento de um determinado tipo de \u00edman antes de finalizar a sua sele\u00e7\u00e3o.<\/p>\n<h3>For\u00e7a de reten\u00e7\u00e3o necess\u00e1ria<\/h3>\n<p>A for\u00e7a de reten\u00e7\u00e3o tamb\u00e9m se refere \u00e0 densidade do campo magn\u00e9tico. N\u00e3o escolha uma for\u00e7a de reten\u00e7\u00e3o superior. A for\u00e7a \u00f3ptima ser\u00e1 a melhor neste aspeto. Uma for\u00e7a de reten\u00e7\u00e3o mais elevada permitir-lhe-\u00e1 ter custos mais elevados e conduzir\u00e1 a um funcionamento incorreto. Se precisa de 35MGOe, ent\u00e3o porqu\u00ea escolher 40MGOe?<\/p>\n<h3>Resist\u00eancia \u00e0 desmagnetiza\u00e7\u00e3o<\/h3>\n<p>Outro aspeto que deve ter em conta ao escolher o tipo de \u00edman espec\u00edfico \u00e9 a resist\u00eancia \u00e0 desmagnetiza\u00e7\u00e3o. A desmagnetiza\u00e7\u00e3o resulta de v\u00e1rios factores, como o calor elevado, o campo magn\u00e9tico e a temperatura de funcionamento. Uma desmagnetiza\u00e7\u00e3o insignificante ou inexistente pode levar a uma opera\u00e7\u00e3o eficaz e mais longa. Escolha o \u00edman que oferece maior resist\u00eancia \u00e0 desmagnetiza\u00e7\u00e3o. Tenha em aten\u00e7\u00e3o que a desmagnetiza\u00e7\u00e3o \u00e9 irrepar\u00e1vel.<\/p>\n<h3>Poder de adsor\u00e7\u00e3o<\/h3>\n<p>Pode referir-se a esta for\u00e7a como uma for\u00e7a que um \u00edman experimenta depois de se fixar na placa de ferro. Em seguida, experimenta uma forte tra\u00e7\u00e3o no sentido da magnetiza\u00e7\u00e3o. Estes pux\u00f5es referem-se a 1 quilograma-for\u00e7a, igual a 9,80 Newton. Considere este fator antes de selecionar o seu grau de \u00edman espec\u00edfico.<\/p>\n<h3>Tamanho e forma<\/h3>\n<p>As formas do \u00edman afectam a dire\u00e7\u00e3o das linhas do campo magn\u00e9tico e o tamanho afecta a intensidade global do campo magn\u00e9tico. Considere o local de instala\u00e7\u00e3o e escolha a forma em conformidade. Existem v\u00e1rias formas de \u00edmanes, tais como redondas, quadradas, segmentadas, an\u00e9is, etc. Tamb\u00e9m pode escolher o n\u00edvel de espessura desejado quando se trata de v\u00e1rios tipos de \u00edmanes.<\/p>\n<h3>Revis\u00e3o da tabela de classifica\u00e7\u00e3o do \u00edman<\/h3>\n<p>Como se pode ver nas sec\u00e7\u00f5es anteriores, h\u00e1 muitas vari\u00e1veis que determinam o sistema de classifica\u00e7\u00e3o. Por exemplo, ir\u00e1 rever:<\/p>\n<ul>\n<li>For\u00e7a dos \u00edmanes onde pode avaliar os materiais dos \u00edmanes juntamente com a for\u00e7a dos \u00edmanes. Geralmente, o neod\u00edmio produz os \u00edmanes mais fortes do mundo. Naturalmente, as suas for\u00e7as tamb\u00e9m variam, como ilustr\u00e1mos acima.<\/li>\n<\/ul>\n<h2>Conclus\u00e3o<\/h2>\n<p>O tamanho e o tipo certos de \u00edmanes s\u00e3o cruciais para garantir a efic\u00e1cia e a efici\u00eancia da opera\u00e7\u00e3o. Agora j\u00e1 conhece todos os tipos de \u00edmanes, benef\u00edcios, aplica\u00e7\u00f5es, graus e carater\u00edsticas.
