I'm modelling components and one of the common aluminium grades here in the UK is 6082-T6. Unfortunately I can not find this in the Materials database.
In addition I do not know how to add a custom material and having searched several posts here none have been of use.
I've even followed a link to add an external database but the instructions are not relevant to SolidWorks 2018's file structure.
Your assistance is greatly appreciated.
