The development of platinum alloys for jewellery applications by considering both the conventional and the advanced manufacturing techniques-review paper [PDF]
The thermophysical properties of platinum (Pt) and its alloys are key when deciding on jewellery fabrication or manufacturing techniques. They include the platinum alloys’ density, viscosity, melting point, thermal conductivity, reflectivity and surface ...

La metalurgia inca: estudio a partir de las colecciones del Museo de América de Madrid
Metallurgy in Inca times reflects a technological heritage of over 2,000 years of metalworking in the vast region of the Central Andes. Copper and its alloys, silver, and gold were widely used metals.

Analysis of Dental Gold Alloys
Complete chemical analyses of about 40 dental gold alloys were made as part of the investigation of their physical properties. These analyses required the determination of silver, gold, platinum, palladium, iridium, rhodium, copper, zinc, nickel, tin, manganese, iron, and magnesium. Methods as found in the literature for the determination of the above-

V. Gold-aluminium alloys [PDF]
This paper is a study of the binary alloys composed of gold and aluminium. The fact that metals in many cases form definite chemical compounds with each other, is becoming increasingly evident as attention is given to the subject. But there are many pairs of metals whose freezing point-curve affords no indication of chemical combination, and which ...
