How are metal alloys bonded
WebA metallurgical assay is a compositional analysis of an ore, metal, or alloy, usually performed in order to test for purity or quality.. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals are assayed by an assay office.Silver is assayed by titration, gold by cupellation and platinum by …
