EBest Circuit (Best Technology) has more than 14 year experience for producing Metal core PCB<\/a>, we have our own raw materials factory for MCPCB and we fabricate MCPCB<\/a> in Shenzhen, so that customer various special requirements can be meet here.<\/p>\n\n\n\n

Compared to copper and stainless steel, aluminum is the most economic option considering thermal conductivity, rigidness, and cost. And many of these aluminum alloys base have been divided into classes, the commonly used on MCPCB<\/a> are AL1060, AL3003, AL5052 and AL6061.<\/p>\n\n\n\n

Do you know the differences between these substrates? This blog will give a brief introduction for you.<\/p>\n\n\n\n

1060 alloys
AL1060 are commercially pure, unalloyed aluminum, it\u00e2\u20ac\u2122s soft, ductile, workability and exceptional corrosion resistance, making it suitable for hard-forming applications. It can be welded with any method, but it cannot be heat-treated. Its cost is the lowest of the four types.<\/p>\n\n\n\n

3003 alloys
AL3003 use silicon, copper, and magnesium as the main alloying elements, oftentimes with supplemental nickel and beryllium. They are heat treatable, have high strength, good resistance to cracking and wear, and have good machinability.<\/p>\n\n\n\n

5052 alloys
AL5052 use magnesium as their primary alloying element and are not heat-treatable, but it\u00e2\u20ac\u2122s the highest strength alloy of the more non-heat-treatable grades. Its resistance to fatigue is better than most grades of aluminum and have a great surface aesthetic when anodized.
In our company, if not special request or notes, the default material we use is AL5052 after considering all the performance and cost.<\/p>\n\n\n\n

AL6061 implement magnesium with silicon as their principal alloying elements. Their strength is improved with heat treatment. AL6061 is one of the most widely used aluminum alloys, it has high strength and superior corrosion resistance. Its weld-ability and formability make it suitable for many general-purpose applications.<\/p>\n\n\n\n

Cost Comparison: AL1060 < AL3003 < AL5052 < AL6061<\/p>\n\n\n\n
