Squeeze the advantages and disadvantages of aluminum, Changzhou aluminum manufacturers - four-ring aluminum summarized as follows:

 
Aluminum is the use of extrusion molding process, that is, aluminum ingots and other raw materials in the melting furnace, after extrusion into the mold extrusion molding, it can also be extruded in a variety of different sections of the profile. The main performance is strength, hardness, wear resistance.

Advantages are: light weight, no rust, design changes quickly, low mold input, vertical elongation up to 10 meters or more. Aluminum surface quality is also more difficult to overcome the defects: warping, deformation, black lines, convex and white and white line. The designer level and mold design, production industry is reasonable, to avoid the above shortcomings.
