INVENTION
Patent of the Russian Federation RU2012605
ALLOYS BASED ON GOLD
Applicant's name: Julia Schepochkina
The name of the inventor: Shchepochkina Julia Alekseevna
The name of the patent owner: Shchepochkina Julia Alexeevna
Address for correspondence:
The effective date of the patent: 1992.03.05
The invention relates to gold-based alloys intended for use in instrument making, jewelry and chemical industries. The alloy contains, wt. %: Gold 58.0 - 59.0; Silver 12.0 - 13.0; Zinc 1.8 - 2.3; Titanium 3.1 - 3.8; Nickel 0,3 - 0,4; Copper the rest. The properties of the alloy are as follows: 
In = 44-48 kg / mm 2 , the number of kinks at an angle of 90º = 
-10.
DESCRIPTION OF THE INVENTION
The invention relates to metallurgy, in particular to gold-based alloys used in instrument making, jewelry, and chemical industries.
Alloys containing gold, silver, and copper are known.
Known is an alloy containing the following components, wt. %: Gold 58.0-59.0; Silver 9.0-11.5; Manganese 2.0-3.5; Zinc 3.0-4.0; Copper the rest (2). Such an alloy is used in the jewelry industry.
The object of the invention is to increase the mechanical properties of the alloy.
The aim is achieved by adding titanium and nickel to the gold-containing alloy containing silver, zinc, copper, with the following component ratio, by weight. %: Gold 58.0-59.0; Silver 12.0-13.0; Zinc 1.8-2.3; Titanium 3.1-3.8; Nickel 0,3-0,4; Copper the rest.
In Table. 1 shows the compositions of the proposed alloy based on gold.
In Table. 2 shows the expected mechanical properties of the proposed alloy.
The technology of obtaining the proposed alloy is the same as the technology of obtaining the prototype alloy.
CLAIM

Gold 58.0 - 59.0
Silver 12.0 - 13.0
Zinc 1.8 - 2.3
Titanium 3.1 - 3.8
Nickel 0.3-0.4
Copper Other
