Audited Supplier Mg-al-zn Zinc Aluminum Magnesium Steel Sheet Alloy Steel Coil For Roofing
Magnesium Aluminum Zinc Alloys are a common type of heat-treatable commercial alloy often used in structural components and metallurgical coatings due to their light weight and high resistance to corrosion. American Elements manufactures magnesium aluminum zinc in varying ratios such as high magnesium (96% Mg, 3% Al, 1% Zn (magnesium AZ31B), and 93% Mg 6% Al, 1% Zn (magnesium AZ61A), high aluminum (0.7-3.4% Mg, 0.8-8.2% Zn, balance Al), or high zinc (93.5% Zn, 3.5% Al, 3% Mg), in addition to custom compositions. Magnesium aluminum zinc is available in a number of different forms, including foils, rods, and other shapes in a range of sizes and dimensions. Magnesium aluminum zinc alloy is generally immediately available in most volumes, including bulk quantities. American Elements can produce most materials in high purity and ultra high purity (up to 99.99999%) forms and follows applicable ASTM testing standards; a range of grades are available including Mil Spec (military grade), ACS, Reagent and Technical Grade, Food, Agricultural and Pharmaceutical Grade, Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia).
A generalized analysis of magnesium-containing coated steel plate for commercial applications shows that the Mg content in most coatings is less than or equal to 3%. Hence, according to the aluminum content of the coatings, the zinc-aluminum-magnesium coatings can be divided into the following types:
l Low-aluminum Zn-Al-Mg coating, with aluminum content of 1-3.5%: This coating is formed by adding a certain amount of aluminum-magnesium and other elements on the basis of hot-dip galvanizing. The coated steel plate has also been tested in a color coating unit, and low-aluminum zinc-aluminum-magnesium plate has also been successfully developed. The coating is an upgraded version of the corrosion resistance of the hot-dip pure zinc coating, which is referred as BZM coated steel plate and its color coated plate.
l Medium-aluminum Zn-Al-Mg coating, with aluminum content of 5~11%.
l High-aluminum Zn-Al-Mg coating, with aluminum content of 55%. The coating is formed by adding certain magnesium and other elements on the basis of hot-dip aluminum-zinc. The coated steel plate has also been tested in a color coating unit, and the color coated steel plate with a high-aluminum zinc-aluminum-magnesium substrate has been successfully developed. This coating is an upgraded version of the corrosion resistance of the hot-dip aluminum-zinc coating, which is referred to as BAM coated steel sheet and its color coated sheet.
