铝合金钢圈生产厂家

有些铝合金有良好的低温性能,在-183~-253[2oc]下不冷脆,可在液氢和液氧环境下工作,它与浓硝酸和偏二甲肼不起化学反应,具有良好的焊接性能,因而是制造液体火箭的好材料。发射“阿波罗”号飞船的“土星” 5号运载火箭各级的燃料箱、氧化剂箱、箱间段、级间段、尾段和仪器舱都用铝合金制造。

Some aluminium alloys have good low temperature performance and are not cold and brittle at - 183 ~ - 253 [2oc]. They can work in liquid hydrogen and liquid oxygen environment. They can not react with concentrated nitric acid and unsymmetrical dimethylhydrazine and have good welding performance. Therefore, they are good materials for liquid rockets. Saturn 5 launch vehicle launching Apollo spacecraft is made of aluminum alloy at all levels of fuel tanks, oxidizer tanks, inter-tank sections, inter-stage sections, tail sections and instrument cabins.
