Aluminium, Commercial Alloy
6026 T9 Bar
Tin free aluminium alloy machining bar recently developed to meet European Environmental Protection Directives.
Aluminium alloy 6026 is a recently developed alloy meeting the following European Environmental Protection Directives:
- 2000/53/CE-ELV – For the automotive sector
- 2002/95/CE-RoHS – For the electrical and electronics sector
Alloy 6026 does not contain Tin (Sn) which can cause weakness and cracking of machined parts when subjected to stress and high temperature. Alloy 6026 is a good alternative to alloys 6061 and 6082. Extruded bars in alloy 6026 have the same minimum tensile strength as alloys 2011 & 2030.
