在国际铅锌研究组织主持下,研究发展的一种新型镀锌材料为Zn-5Al合金,其中还含有少量铈和镧,取名为Galfan。其耐腐蚀、延性、可焊性及镀着性能等均优于常规的镀锌材料。与Al-43.5Zn-1.5Si高铝镀层材料相比具有更好的散边和划痕保护作用。最近,在沸腾钢、连铸钢和铝镇静钢共120吨 Under the auspices of the International Lead and Zinc Research Organization, a new type of galvanized material for research and development is Zn-5Al alloy, which contains a small amount of cerium and lanthanum and is named as Galfan. Its corrosion resistance, ductility, solderability and plating performance are better than conventional galvanized materials. Compared with Al-43.5Zn-1.5Si high-aluminum coating material has better edge and scratch protection. Recently, 120 tons of boiling steel, continuous cast steel and aluminum killed steel were produced
