Low melting carat gold brazing alloys for jewellery manufacture

The Hardening of Platinum Alloys for Potential Jewellery Application

60) to be used for fabricating jewellery, so alloying additions are made to increase the hardness. Platinum jewellery alloys usually have platinum contents of 90 wt.% and higher. The most common alloys are hallmarked as 950 platinum (95 wt.%). Unlike carat gold (Au) jewellery alloys, where relatively large additions can be made (to alter the properties of the alloy such as its hardness or colou...

A Tool for a High-Carat Gold-Standard Word Alignment

In this paper, we describe a tool designed to produce a gold-standard word alignment between a text and its translation with a novel visualization. In addition, the tool is designed to aid the aligners in producing an alignment at a high level of quality and consistency. This tool is presently being used to align the Hebrew Bible with an English translation of it.

Wettability of Brazing Filler Metals on Copper and Copper Alloys

The possibility of alloying can not be avoided at the interface between molten brazing filler metal and base metal in brazing, so the wettability of brazing filler metal can not be easily explained theoretically. We used the original apparatus for wettability test and investigated the relation between the wettability of brazing filler metals of Ag-P-Cu and Ag-Cu-Zn-Cd systems on copper and the ...

Microwave Sintering, Brazing and Melting of Metallic Materials

Microwave energy has been in use for variety of applications for over 50 years. These applications include communication, food processing, wood drying, rubber vulcanization, medical therapy, polymers, etc. In the last two decades microwave heating has been also applied very effectively and efficiently to heat and sinter ceramic materials. Microwave heating is recognized for its various advantag...
