4007 H28 round aluminum bar Aluminum rod is a type of aluminum product, and the melting and casting process of aluminum rod includes melting, purification, impurity removal, degassing, slag removal, and casting. According to the different metal elements contained in aluminum rods, they can be roughly divided into 8 categories. Aluminum round rod is an aluminum rod with a circular shape.4007 H28 round aluminum bar is the Aluminum Association (AA) designation for the material. In European standards it will be given as EN AW-4007. Also, the EN chemical name is AlSi1,5Mn. The UNS number is A94007.

4A01 H18 round aluminum bar has a large thermal expansion coefficient, high high temperature strength, and good high temperature corrosion resistance. For machining forged pistons. It is a building material, a forging material for mechanical parts, and a welding material; 4A01 aluminum-silicon alloy 1. High wear resistance. Aluminum-silicon alloy has high wear resistance. With the increase of silicon content, the hardness and strength of aluminum-silicon alloy will increase accordingly. 2. Small coefficient of thermal expansion. Any material will expand at high temperature, which limits the application range of most materials. The aluminum-silicon alloy has a small thermal expansion coefficient and can work in a high-temperature environment. 3. Easy to cast. Among the cast aluminum alloys, 4-series aluminum-silicon alloys account for more than 90%, which shows the superior casting performance of aluminum-silicon alloys.
