Product Description

High Precision 99 Alumina Ceramic Components Machining Parts

 
 

1. Description:

The main applications and some of the foundry products which are used in aluminium casting and processing. 1) Building and Construction: Aluminium is used in building and construction frequently, in order to produce roofs, bridges and a variety of other structures. Even though it is difficult to weld, landings, cladding and stairways are also often made using aluminium as it is extremely malleable and can be easily shaped. High rise buildings would not be possible without aluminium due to its high strength to weight ratio. 2) Power Lines: Power lines often span hundreds of meters between towers, so overhead cables must be cost-effective. Copper wires are frequently used, however, aluminium overhead cables are half the weight of their copper counterparts and six times cheaper whilst still offering the same electrical resistance properties.

2. Feature Advantages:

1) High elasticity modulus

2) High compressive strength.

3) Anti corrosion

4) Abrasion resistance

5) Impact resistance

6) High precision
