MECHANICAL WORKING ALLOYS FOR YELLOW GOLD

yellow gold alloys

Jewels that are lighter, thinner, harder, easier to produce... How to combine all these requests from our customers in a product? Well, that is our everyday work! Here are some of the latest formulations we developed for the production of jewellery by mechanical working processes.

B182T

Title: 750‰

Formulation: Ag 63%, Zn 2%

Hardness (as cast/after age-hardening 300ºC x 90'): 130 HV / 180 HV

Features:

  • Highly deformable, easy to process
  • Perfect on CNC milling and continuous casting processes
  • Light yellow color (2N, "Italian" color) with extremely high shininess
 

YG281U

Title: 750‰

Formulation: Ag 34%, Zn 15%

Hardness (as cast/after age-hardening 450ºC x 90'): 135 HV / 210 HV

Features:

  • As low as 34% silver in the formulation!
  • Casting in closed systems, sheet and wire deformation
  • Light yellow color
 

Y298T

Title: 585‰

Formulation: Ag 22%, Zn 13%

Hardness (as cast/after age-hardening 450ºC x 90'): 140 HV / 190 HV

Features:

  • Conceived for making TIG tube in 585‰. Can be used also in 375‰
  • High chemical resistance to hollowing
  • Harder and more thermally resistant than similar products in the range
 

Y144HN

Title: 375‰

Formulation: Ag 18%, Zn 13%

Hardness (as cast/after age-hardening 450ºC x 90'): 150 HV / 195 HV

Features:

  • Conceived for making TIG tube and hollow chain. Can be used also in 585‰
  • Good chemical resistance to hollowing
  • Good thermal resistance to annealing cycles
