Classification of aluminium rods
1, according to the content of alloy elements in different aluminum sheet can be divided into: 1 * * * for industrial pure aluminum (Al), 2 * * * for Al Cu alloy aluminum (Al--Cu), 3 * * * aluminum manganese alloy aluminum (Al--Mn), 4 * * * for aluminum (aluminum silicon alloy Al--Si), 5 * * * for aluminum magnesium alloy aluminum (Al--Mg), 6 * * * for Al Mg Si alloy aluminum (AL--Mg--Si), 7 * * * for aluminum and zinc alloy aluminum [AL--Zn--Mg-- (Cu)], 8 * * * for aluminum and other elements.
third, fourth digits representing the lowest content of pure aluminum content percentage after the decimal point.2, according to the shape can be divided into: round aluminum bar, square aluminum rod, six angle aluminum rod, trapezoidal aluminum rod.
Each series but also with three bits, each bit must be numbers or letters, the meaning is: second digit number controlled impurities;
