Welding and riveting are two associated operation procedures in the production process of structuralmetallicmaterials.
铆接工艺中的展开放样、下料、加工成型和连接装配等过程能产生强烈的机械性噪声。
2
Magnesium alloys are the lightest structuralmetallicmaterials, which can be used to reduce the weight of military equipments and improve their performance.
镁合金是最轻质的金属结构材料，是实现军事装备轻量化和提高军事装备各项性能的理想材料。
3
The density of magnesium and its alloys is yelatively low, only accounts for 64% of aluminum density and 25% of steel density, and it is one of the lightest structuralmetallicmaterials.
