Al99.7E High quality Aluminum Ingot

Aluminum is a silver-white metal, the third most abundant in the earth's crust after oxygen and silicon. The density of aluminum is relatively small, only 34.61% of iron and 30.33% of copper, so it is also called a light metal. Aluminum is the world's largest non-ferrous metal after steel in production and consumption. The density of aluminum is only 2.7103g/cm³, which is about 1/3 of the density of steel, copper or brass. Due to its light material, aluminum is often used in the manufacture of land, sea and air vehicles such as automobiles, trains, subways, ships, airplanes, rockets, and spaceships to reduce its own weight and increase its loading capacity.

Product Description

Aluminium ingot is a unit of measurement with a fixed size and a fixed purity. It is produced by electrolysis from alumina-cryolite, and there are two categories of aluminum ingots after they enter into industrial applications: cast aluminum alloys and deformed aluminum alloys. Cast aluminum and aluminum alloys are castings produced by casting methods; wrought aluminum and aluminum alloys are processed products produced by pressure processing methods: plates, strips, foils, tubes, bars, shapes, wires, and forgings. According to the national standard Aluminum ingots for remelting are divided into 8 grades according to chemical composition, namely Al99.90, Al99.85, Al99.70, Al99.60, Al99.50, Al99.00, Al99.7E, Al99. 6E.

Aluminum ingots are widely used in construction, power, packaging, transportation and daily consumer goods, etc.

Aluminum Alloy Ingot

Definition

It uses pure aluminum and recycled aluminum as raw materials, and adds other elements according to international standards or special requirements, such as: silicon (Si), copper (Cu), magnesium (Mg), iron (Fe)..., to improve the castability of pure aluminum, chemical Alloys formulated with insufficient properties and physical properties

Application

Application of Cast Aluminum-Silicon (Al-Si) Alloy

Aluminum-silicon (Al-Si) alloy, generally the mass fraction of Si is 4%~22%. Because Al-Si alloy has excellent casting properties, such as good fluidity, good air tightness, small shrinkage and low heat tendency, After modification and heat treatment, it has good mechanical properties, physical properties, corrosion resistance and moderate machinability. It is the most versatile and widely used alloy in cast aluminum alloys.

Production Process

The production of aluminum ingots consists of production links such as bauxite mining, alumina production, and aluminum electrolysis.

First, the bauxite is mined, and the bauxite powder is produced by washing, grinding and other processes, and then the alumina is obtained through four complex processes such as roasting. There are three main types of bauxite for alumina production: gibbsite, a Hydraulic stone, boehmite.
