The difference between aluminum alloy and zinc alloy

[China Aluminum Industry Network] Aluminum-based alloys collectively. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the minor alloying elements are nickel, iron, titanium, chromium, and lithium.
Aluminum alloy has low density, but high strength, close to or more than high-quality steel, good plasticity, can be processed into a variety of profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use is second only to steel .
Aluminum alloys are divided into two major categories: cast aluminum alloys, which are used in the as-cast state; deformed aluminum alloys, which are able to withstand pressure processing, have higher mechanical properties than as cast. Can be processed into various forms and specifications of aluminum alloy. Mainly used in the manufacture of aviation equipment, daily necessities, construction windows and doors.
Based on zinc, alloys of other elements are added. Often added alloy elements are aluminum, copper, magnesium, cadmium, lead, titanium and so on. Zinc alloys have a low melting point, good fluidity, easy fusion welding, brazing and plastic processing, corrosion resistance in the atmosphere, and easy recovery and remelting of residuals; however, they have low creep strength and are prone to natural ageing and cause dimensional changes. Melting method, die casting or pressure processing into the material. According to the manufacturing process can be divided into cast zinc alloy and deformed zinc alloy.
The main additive elements of zinc alloys are aluminum, copper and magnesium. The zinc alloys can be divided into two types of deformation and casting zinc alloys according to the processing technology. Cast zinc alloys have good fluidity and corrosion resistance and are suitable for die casting instruments and automotive parts. Wait.
【Zinc Alloy Composition and Casting Quality】
First, the characteristics of zinc alloys 1. Significant.
2. Casting performance is good, can die-casting complex shape, thin-walled precision parts, casting surface is smooth.
3 can be surface treatment: electroplating, spraying, spray paint.
4. It does not absorb iron when it is melted and die-cast, it does not corrode, and it does not stick.
5. There is a good room temperature mechanical properties and wear resistance.
6. It has a low melting point and melts at 385°C, making it easy to die-cast.

Okan Hardwood Flooring

The heartwood is yellow-brown and becomes red-brown with air. The sapwood is clearly demarcated. The grain is interlocked and the texture is medium.

Okan is very durable to fungi and is durable to dry wood borers; sapwood demarcated (risk limited to sapwood). Due to its high specific gravity and hardness, this species naturally covers the biological hazard class 5 (end-uses in the marine environment or in brackish water).
