In the recent past, Platinum Guild International has identified several issues relating to the use of improper platinum alloys for specific manufacturing methods. Rings made from soft alloys would scratch rapidly, some would deform, others would dent, etc. The underlying causes of these issues can be addressed by clarifying which alloy is best suited for which function. This paper will address the suitability of individual platinum alloys for different manufacturing methods, ranging from fabrication to casting, die-striking to machining. Comparing hardness, strength and durability, the ideal platinum is identified and recommended for the specific manufacturing method. Specialty alloys and their uses in manufacturing will also be discussed.
