4xxx series are low ductile alloys, due to the high silicon content of these alloys, silicon is present in the form of intermetallic precipitates, but also as elemental silicon particles making the material brittle.7xxx series are very strong "heat treatable" alloys; they can be strengthened through heat treatment based on the combination of zinc and magnesium.

Typical Applications

Processes & Equipment

Aluminum 4&7 Series

Good Performance


We can extracted thin-layer alumina with the thickness of 5~20μm from aluminum plate in chemistry experiments. This product is characterized by high hardness, insulativity, high thermal conductivity, resistance to corrosion and adsorption capacity.

Aluminum 4&7 Series

High Safety


Our products are known for its low density, lack of toxicity, high thermal conductivity and resistance to corrosion. There are no residues on the surface of alumimum sheet and  no poisonous gases during the production. All of our products can meet national standard.

Aluminum 4&7 Series

Slitting machine was completed and put into production in October 2010, and it was designed and installed by Liaoning Machinery Institution. Hard tooth surface gear transmission with high precision and stability was adopted in machinery. Hydraulic drive was applied in the conical head and driving device.
