The cost of brass is a bit much but I love the sound and was thinking of making large footers, at least 2 inch dia. Any metal come close to brass? Iron, steel, al.??? Thanks, Tweaker

Brass has a lot of properties that are not present in other materials -
Additionally there are many "flavors" of brass and many different Tempers, or hardness:
Cast Brasses: Red Brass, SAE #40; Yellow Brass, SAE #41; Cast Brass-to be brazed, SAE #44
Wrought Brass: Commercial Brass Sheet, SAE #70 - which comes in grades A-C, and temper: Quarter Hard, Half Hard, 3/4 Hard, Hard, Extra Hard, Spring, Extra Spring.
Wrought Rod: SAE #72, Naval Brass (Tobin Bronze) SAE #73, and SAE #88
Some of the Aluminum alloys would be closer, but they will bear similar costs as the alloying materials are the same, or the different ones are even more expensive.
Bronze would be more similar, but this will not get price relief - same alloying agents...
Good Luck, and
Happy Listening
I use and enjoy classic J.A. Michell Engineering Small Tenderfeet machined billet aluminum cones, and the Nerve Audio equivalent of the Large Tenderfeet machined billet aluminum cones. When implemented in conjunction with other vibration control devices such as Herbie's Audio Lab compliant pads, metal coupling discs, and wooden platforms, the contribution of the aluminum cones seem to provide what I consider to be a relatively transparent, quick sonic signature.
I use hockey pucks under my power amps and speakers. They are wonderful and cost $1.00 each. No brass in them

A new product line is born, Silver Footers!
Thank you
Probably mild steel would have similar hardness....and it's cheap.
