The BIG weekend tweak!

Brass & aluminum have very similar requirement protocol related to plating and base coats required and can also be a 3 or 4 plate layer foundation. However whereas 6061 aluminum has just under half the tensile strength of brass, 7075 aluminum is 30% higher tensile strength and stronger than brass. S'why its commonly referred to as 'poor man's Titanium.'

I'm still trying to figure out how my metals sample picked up a 1% bauxite content. The primary ore in aluminum in a case void of any aluminum!?! Guess that's why there's a 1% margin for error factored in or I didn't get my sample collecting tap as clean as I thought

Couldn't be because it is aluminium could it? My speakers are made of aluminium but they are very heavy do you think they might be made of brass as well?
