Aluminum Types of Aluminum PCB

Regarding Aluminum PCB or wrote as Aluminium PCB, there are different types of Aluminum which used for the laminate of Aluminium base pcb, the brief introduction as below,

There are mainly three different types of metal aluminum base that commonly used, including 1000 series, 5000 series and 6000 series, the basic features of these three series aluminum base are as follows:

(1) 1050, 1060, 1070 are the typical types of 1000 series, 1000 series is also known as pure aluminum base, which is the purest of all the series, the purity can reach more than 99.00%. Because this series do not contain other technical elements, so the production process is single and simple, the price is relatively cheap as well, It is currently the most commonly used series in conventional industry. nowadays, 1050 and 1060 are most widely used in the market. 1000 series aluminium base determine the range of the minimum aluminium content according to the last two digits, such as series 1050 , the last two digits are 50, according to the international brand naming principles, its aluminum content must be more than 99.5%, it is unqualified if less than 99.5%. Our country standard (GB/T3880-2006) is clearly stipulated in 1050 must reached 99.5% aluminum content. Same as 1060 series that aluminum content must be above 99.6%.

(2) 5000 series include 5052, 5005, 5083, 5A05 series. 5000 series belongs to alloy aluminum base series which is commonly used, the main elements is magnesium, about 3-5% magnesium element, so it is also known as aluminum and magnesium alloys. The main features are low density, high tensile strength and high elongation rate. Under the same area, the weight of the aluminum magnesium alloy is lower than other series, so is the reason why often used in aviation, such as aircraft fuel tank. In other conventional industries are widely used as well. The processing technology belongs to the series of hot rolled aluminum base, therefore can do oxidation processing. At present, 5052 is the most widely used in 5000 series.

(3) 6061 belongs to 6000 series, which mainly contains magnesium and silicon two kinds of elements. 6061 is a kind of cold treatment of aluminium products, applicable to against corrosion, oxidation demanding. The general characteristics of 6061: excellent interface characteristics, easy to coating, high strength, good workability, strong corrosion resistance. 6061 aluminum base typical applications: aircraft parts, camera parts, coupler, ship accessories and metal, electronic components and connectors, etc.

According to the technology Aluminum / Aluminium PCB board can be categorised: HASL Aluminum PCB, OSP Aluminium PCB, silver plated Aluminum PCB, immersion gold Aluminum PCB, etc. According to application Aluminum PCB can be categorised: street light Aluminum PCB, LED Aluminium PCB, LB Aluminum PCB, COB Aluminium PCB, packaging aluminum PCB, power supply Aluminum PCB, automotive aluminum PCB and so on.
