今日はアルミニウムについて少しお話しましょう. アルミニウムは軽金属です, そしてその化合物は自然界に広く分布しています, 酸素とケイ素に次ぐ. 金属の種類の中でも, 鋼に次ぐ, それは金属の中で2番目に大きいカテゴリーです. アルミニウムは優れた導電性と延性を持っています, そしてその応用範囲は非常に広いです, involving light industry, 電力, 電気, エレクトロニクス, 自動車, 機械製造, 工事, packaging and other industries.
The most attention we pay is to the price.
What factors will influence the price of the aluminum? Let’s see (1) production and import and export volume; (2) inventory; (3) the level of electricity; (4) the degree of application of related alternative products; (5) the improvement and innovation of production processes.
There are many metals, but aluminum is more suitable for futures trading, why? Please check below: 初め, large number of production and sales, with a large number of buyers and sellers; 2番, uniform quality, simple specifications, easy to classify the grade; third, easy to store, convenient transportation; fourth, price fluctuations
Overview of international and domestic transactions: The largest exchange of aluminum contracts in the world is the London Metal Exchange (LME), the Shanghai Metal Exchange is one of the more influential exchanges. So for customers abroad, they mainly check prices based on the LME, and for chinese factories, they check prices based on SME.
Compared with other metal materials of aluminum and aluminum alloy, it has the following characteristics:
1, high intensity
Aluminum and aluminum alloys have high strength. After a certain degree of cold working, the strength of the substrate can be strengthened, and some grades of aluminum alloy can also be strengthened by heat treatment.
2, 良好な電気伝導性と熱伝導性
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3, easy for processing
特定の合金元素を添加した後, a cast aluminum alloy with good casting properties or a deformed aluminum alloy with good plasticity can be obtained.
4, 低密度
The density of aluminum and aluminum alloys is close to 2.7 g/, それは約です 1/3 鉄や銅の.
5, 良好な耐食性
It is easy to naturally produce a dense and strong protective film on the surface of aluminum, this film can protect the substrate from corrosion. By artificial anodizing and coloring, a cast aluminum alloy with good casting properties.
