MATERIAL PROPERTIES (NONFERROUS METALS)
As for the materials (workpieces) to be processed by the turret punch press, this time,
we summarized non-ferrous metals, following the previous steel.

ALUMINIUM AND ALUMINUM ALLOY
Aluminum and aluminum alloy is lightweight and resistant to rust, so it is used for various purposes invarious fields such as lighting fixtures, electric appliances, building materials, various containers,
accessories and aircraft materials.

2Heat treated alloy with high strength.
Over 12 - 17 Aircraft materials, various structural materials, etc.

Typical alloy with moderate strength.

One of the alloys with the highest strength in aluminum alloy.
It is also used as a mold material for injection tooling.
2(The tensile strength of SPCC 270N/mm or more)

Aluminum is a material with relatively good workability, but because of its softness,
marks like a guide may stick to the workpiece or burrs may occur during punching.
Adjustment such as weakening the force holding the work (spring strength) orreducing the clearance may be necessary. (Please refer to Technical Information Vol. 22)
