The difference between aluminum wall panels and cast iron for carding machine

Difference in volume, aluminum specific gravity is light, the unit volume of cast aluminum parts structural strength is less than cast iron parts, so the volume of aluminum castings under the same strength than the volume of cast iron parts. In the case of the same volume, the volume of cast aluminum parts is smaller than cast iron parts.

3, the difference in cost, now cast aluminum parts (including heat treatment) of the market price of about 38,000 yuan / ton, the price of cast iron parts about 6500 yuan / ton.

4, the difference in heat dissipation, cast aluminum parts of the thermal conductivity of cast iron parts is more than three times, in industry has been widely used in radiators, heat exchangers and cookware.

5, the difference in corrosion resistance, cast aluminum parts of the surface of a layer of corrosion-resistant oxide protective film, it is difficult to protect the aluminum castings are corroded, so aluminum castings are also widely used in medical equipment, refrigeration equipment, oil and gas pipelines, petroleum machinery and so on. The corrosiveness of cast iron parts is far less than cast aluminum parts.

6, casting performance difference, aluminum casting performance is higher than cast iron, aluminum is easy to casting molding, casting complex shape of the casting blank.

7, we found that the production of cast iron parts of the production line covers an area of large, environmentally polluting, complex processing technology. And cast aluminum parts of the production characteristics of the opposite. So from the perspective of market competition, cast aluminum parts have certain advantages. But from the current situation, the market price of aluminum is not low, which limits the cast aluminum parts in the production and processing advantages.
