Aluminum alloy 6061

 

6061 aluminum alloy is a high quality aluminum alloy product produced by heat treatment pre-stretching process. Although its strength cannot compare with that of 2XXX series or 7XXX series, its magnesium and silicon alloys have many characteristics.

 

Material advantages: excellent machining performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy color film, excellent oxidation effect and other good characteristics.

 

2.7075 aluminum alloy

 

7075 aluminum alloy is a cold treated forging alloy, high strength, far better than mild steel. The 7075 is one of the most powerful alloys commercially available.

 

Material advantages: general corrosion resistance, good mechanical properties and anodic reaction. Fine grains make deep drilling better, tools more wear resistant, and thread rolling more distinctive.

 

 

3. The copper

 

Pure copper (also known as red copper) is a tough metal with excellent electrical conductivity and a rosy red surface. It is not pure copper, it contains 99.9% copper, and some other elements are added to improve the surface and performance.

 

Material advantages:

 

It has good conductivity, heat conduction, ductility, deep drawing property and corrosion resistance. Copper conductivity and thermal conductivity is second only to silver, widely used in making conductive and thermal equipment. Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid). It is used in chemical industry.

 

4. The brass

 

Brass is an alloy of copper and zinc. Brass made of copper and zinc is called brass.

 

Material advantages: high strength, high hardness, strong chemical corrosion resistance. The mechanical properties of cutting are also more prominent. Brass has strong wear resistance. Special brass is also called special brass. It has high strength, high hardness and strong resistance to chemical corrosion. The mechanical properties of cutting are also more prominent. Made of brass by the seamless copper tube, soft, strong wear resistance.
