2A12铝棒实心铝棒 超大铝棒厂家直销

2系2A12铝棒
2A12实心铝棒为一种高强度硬铝,可进行热处理强化,在退火、刚淬火和热状态下可塑性中等,点焊焊接性良好，用气焊和氩弧焊时有形成晶间裂纹的倾向;合金在淬火和冷作硬化后可切削性能尚好，在退火状态时不良。抗蚀性不高,常采用阳极氧化处理与涂漆方法或表面加包铝层以提高抗腐蚀能力。

2A12超大铝棒来源历史：
铝（Al）是一种轻金属，其化合物在自然界中分布极广，地壳中铝的资源约为400～500 亿吨，仅次于氧和硅，居第三位。在金属品种中为第一大类金属。铝具有特殊的化学、物理特性，不仅重量轻、质地坚、而且具有良好的延展性、导电性、导热性、耐热性和耐核辐射性，是国民经济发展的重要基础原材料。
铝是地球上含量极丰富的金属元素，其蕴藏量在金属中居第1位。至19世纪末，铝才崭露头角，成为在工程应用中具有竞争力的金属，且风行一时。航空、建筑、汽车三大重要工业的发展，要求材料特性具有铝及其合金的独特性质，这就大大有利于这种新金属－－铝的生产和应用。

2A12 large aluminum rod source of history:
Aluminum (Al) is a kind of light metal, the compounds are widely distributed in nature, in the earth's crust aluminum resources is about 400 ~ 500 tons, second only to oxygen and silicon, ranking the third place. As the first major class of metal on metal species. Chemical, physical characteristics of aluminum has, not only light weight, texture hard, but also has good ductility, electrical conductivity, thermal conductivity, heat resistance and resistance to nuclear radiation, is an important basis for national economic development of raw materials.
Aluminum is extremely rich in content of metal elements in the earth, the reserves ranking the first place in the metal. At the end of the nineteenth Century, aluminum to cut a striking figure, become competitive in the engineering application of metal, and be all the rage the go. The development of aviation, construction, automotive three major industrial, unique properties of material properties of aluminum and its alloy, which greatly facilitates the new metal, aluminum production and application.
2A12 aluminum rod chemical composition of silicon Si: ≤ 0.50 copper Cu:3.8 ~ 4.9 mg Mg:1.2 ~ 1.8 Zn zinc manganese: ≤ 0.30 Mn:0.30 ~ 0.9 Ti ≤ 0.15 nickel titanium:: Ni ≤ 0.10 Fe:0.000 ~ 0.500 iron iron + Ni Fe+Ni: 0 ~ 0.500;
2A12 aluminum rod and uses: used in the requirements of high strength and hardness (including high temperature). Forging, plate and extrusion materials for aerospace structures of heavy, multistage rocket first stage fuel tank and spacecraft parts, wheels, truck frame and suspension parts.
