A1070铝、统称工业纯铝、铝含量约99.8%

A1070 aluminum,collectively referred to as industrial pure aluminum,aluminum content of about 99.8%

 

 

材质成分

Material composition

ADC12、铝含量90%左右、硅含量7-9%还有其他的镁、锌、铁等

ADC12,aluminum content of about 90%,silicon content of 7-9% and other magnesium,zinc,iron,etc.

*LED防爆灯冷锻散热的综合性能优于车铝和压铸铝。同样体积形状的冷锻纯铝散热、可以用于更大功率灯具的散热(比如传统的散热器做100W、冷锻的散热器可以做到150W)
