Aluminium is a silvery white reactive metal which is usually covered in oxide. The oxide makes it inert to acids, but it is attacked by alkali. It is extracted from Bauxite by electrolysis of the oxide dissolved in molten sodium hexafluoroaluminate. The metal has good thermal properties and is malleable and ductile. During the 19th … Read more
Pproblems using durafix welding rod on 6082 aluminium, I was just getting it too hot.
If you want to weld aluminium then you really need a TIG welder… Some jobs are not suitable for TIG welding and a soldering or brazing would be more useful where you can flood a volume with metal. The example here is the bracket that supports the table on my miniature pillar drill. I originally … Read more
I always find machining aluminium to be mostly ok, but now and again milling can just go badly wrong if the chips stick to the tool. The following list of alloys will give you an idea as to how the different alloys can be used. 1000 99% or higher purity excellent corrosion resistance high thermal … Read more
