ISO 15093:2015 specifies an analytical procedure for the determination of either platinum in platinum jewellery alloys, gold in gold jewellery alloys, or palladium in palladium jewellery alloys, with a nominal content of each precious metal of 999 ? (parts per...

Introduction Continuous casting of non-ferrous metals applying the closed head immersed die system with intermittent pulse withdrawal has been practised for well over 100 years. The first patents covering vertical casting of non-ferrous metals was in 1840-43 by Sellers" and Laign '...

1.1 This specification covers general requirements common to wrought precious metal electrical contact alloy products in the form of sheet, strip, wire, and rod. Unless otherwise specified in the purchase order or in an individual specification, these general requirements shall...

Primarily for use as filler metal for gas-metal-arc and gas-tungsten-arc welding, including repair welding, of aluminum alloy castings. Where casting service conditions require good corrosion resistance, maximum strength, and homogeneity, filler metal should be of...

The rapid revolution in modern industry has led to a significant increase in waste at the end of the product lifecycle. It is essential to close the loop, secure resources, and join up the circular economy. This book provides a detailed review of extraction techniques for urban mining of...

This specification covers all nickel-copper-aluminum alloy wrought forms formerly classified as class A. This alloy is designated under the Unified Numbering System for Metals and Alloys as UNS N05500. Except for cases where nonmagnetic properties are paramount,...
