Since silver and alloy prices fluctuate widely, please call us for accurate pricing information. In general we charge a fixed labor fee above the cost of the silver (or any expensive exotic materials) used in the alloy. 

We have many alloys not listed here. Call Keith or Daniel to discuss other types of alloys and custom formulas.

 

How You Can Select An Alloy

 

First, what karat, and color ? Then ask yourself what processes the gold will undergo Will you be casting and finishing or making sheet or wire for forming or fabrication? Keep in mind that you want "ND" alloys for any rolling, stamping, or fabricating process. Casting and recasting gold requires the silicon deoxidiser we use in the casting alloys. This helps provide cleaner castings and helps avoid cyanide stripping. If you use a gas torch- We suggest natural gas, methane, or hydrogen for gold and silver alloys. Or if you use electricity to melt, we strongly suggest the best available way to keep the air away from hot gold or silver. Protect your molten gold! 

If you need more help, call and ask for our "Basic Metallurgy /Alloy Guide For Jewelers- Written by Daniel and printed by us here at PMWest.
*P.O.V. = Pressure Over Vacuum like Neutec, Yasui, and Galoni Equipment.

Have a formula you like? Bring it to us and we’ll manufacture it with our deox and methodology. Discounts do apply for large orders. Call Keith or Daniel for details. 1-800-999-7528 Daniel@preciousmetalswest.com
