The high strength aluminum plate G.AL® C330R is made from alloy EN AW 7021 (AlZn5.5Mg1.5) with material temper T79. It’s sawn on all sides and characterized by low-stress, high strength and high hardness. The uniform strength makes G.AL® C330R a great material choice in industrial and manufacturing sectors.
Applications
Tool Making
The high strength of G.AL® C330R make it ideal for highly-loaded components like tool changers (revolver magazine) for turning machines.
Mold Making
The high thermal conductivity of G.AL® C330R reduces cycle times in foaming, blowing, deep drawing, RIM, and injection molds (low and medium pressure).
Automation
In highly-loaded components such as jigs and swivel devices, G.AL® C330R replaces rolled plates with risidual stress.
Mechanical and Special Machine Engineering
Easy machining and dimensional stability make G.AL® C330R a safe and time-saving material for creating holders, clamping devices, and any other components requiring high degrees of machining.
Handling Machines
Preferably, tool and component carriers are made of low-stress and wear-resistant Al materials. G.AL® C330R plates are a perfect choice.
Thermal Stress
High-strength aluminum alloys tend to undergo irreversible loss of strength and structural changes when operating in temperatures above 190 °F. G.AL® C330R can be used permanently at 250 °F and for short periods (4 – 6 h) up to 280 °F without damage. The material can even withstand temperatures up to 320 °F for 1 – 2 h.
All high-alloyed materials are very sensitive to contact corrosion, especially when steel, copper, brass or bronze was previously used on the CNC machines. In most cases, the pH value is well above 8.5. To avoid contact corrosion, components should be taken off the machine immediately after machining and thoroughly cleaned and dried.
