马克兰材料研究所研制成本种新型的鸽铝合金，该合金具有很高的耐磨性和耐电弧性，特别适用于制作导电触头和熔化焊条．用这种合金制造的导电胜头，其使用寿命要比奇钥、黄铜等铜制触头延长5～10倍，用它制造的电焊条，不仅可以提高焊接质量，而且可降低焊条的消耗．这种合金是
The Markland Institute for Materials developed a new pigeon aluminum alloy that is highly abrasion-resistant and arc-resistant and is especially suitable for the production of conductive contacts and fusion electrodes. Conductive windings made of this alloy have a service life that is 5 to 10 times longer than that of copper keys such as odd keys and brass, and welding rods made of it can not only improve the welding quality but also reduce the consumption of the welding rod . This alloy is
