Aluminum

Gage systems made of aluminum have a big advantage compared with steel gage systems: the weight! Especially for large thread diameters easy to handle gage systems are essential for frequent usage. But there is a trade-off between weight and the coefficient of linear expansion of aluminum compared to graphite electrodes

vs.

which has to be taken into account.

Decom Gages systems made of aluminum have the following specifications:

AlMg 4.5 Mn 0.7, hard coated and PTEE lined (HC-Plus)
Material code 3.3547

All our aluminum blanks are "Made in Germany" and are audited in our in-house laboratory before processed.
