White Brass

They were from 2 old lamp bases I picked up yesterday. They were painted brass color, but scratch test came out silver. The 2 pieces come to 7 1/4 lbs. To heavy to be cast.

Monel one of the nickel alloys is slightly red it;s weired stuff slightly magnetic at room temperature and maybe more magnetic near welded seams or where a hole has been drilled or cut with a plasma,, virtually no spark, test with nitric acid turns green before being overcome with the copper content which eventually turns a pretty aqua blue almost turquoise.

On monel scrap look for traces of green oxides, this will be nickel that has reacted with the surrounding atmosphere.

Monel is commonly used for high end bathroom fixtures, kitchen sinks, pump impellers, boat propeller shafts. But is so tricky to truly identify most of us including me sell it as stainless steel scrap. The yards that own an XRF can identify these nickel alloys, bit I'm sure that they will not test every bit if Stainless you bring in on a whim.

We the junk man would have to know the metal and presort. If your yard says monel and inconel are bought as stainless, save it and find a buyer who specializes in nickel scrap, $7.00 a pound nothing to sneeze at.

Not much help on this stuff as I'm trying to learn more about nickel myself.

First call to follow up on my Monel, $4.00 a pound, the alloy is 60 percent nickel 30 percent copper with some iron. I think that I can do better on price will have to wait until Monday to check on my second sample.
