Abstract
The present invention relates to copper base alloy materials for imitation gold decoration, which comprises zinc, aluminium, titanium ro chromium, nickel, tin, manganese or phosphorus and mischmetal except copper, or also comprises nickel, aluminium, manganese and mischmetal except copper. The present invention has vivid color, and is similar to gold and K gold. The atmosphere resistance, the perspiration resistance and the wear resistance of the present invention are all superior to those of gold and K gold. The present invention can not change colour when used for a long time, has good mechanical and processing performance, and can be processed into boards, wires and profiled bars, which have various shapes. The present invention can be used for manufacturing eyeglass frames, pen caps, nibs, watch cases, clock cases, watch bands, ornaments for lamps and lanterns, jewelry, handicrafts and various building ornaments. Besides, the cost of the present invention is only 1/3 of that of the existing rare gold materials.
Description
The present invention relates to copper base alloy, particularly a kind of copper alloy used for gold-like decorative purpose.
Gold Yin Seze beauty, graceful generous and always be the main raw of making senior jewellery, artwork etc., but price of gold costliness, so people replace gold with regard to the imitation gold copper-base alloy of having developed color and luster and exactly liking gold, and this imitation gold copper-base alloy more and more is subjected to people's welcome.This all there is research both at home and abroad.Abroad make referrals in new 500 Japanese yen currencies of dissection one literary composition according to the 1st the 34th page of Japan's " metal " nineteen eighty-three the 53rd volume, France adopts copper 92%, nickel 6% and 10 Francs of coin of aluminium 2% alloy system (reddish yellow gold), West Germany adopts the skin (light golden yellow) of copper 81%, zinc 10% and nickel 9% alloy system 10 mark's coin, and Austria adopts copper 92%, aluminium 6% and nickel 20 shillings of coin of 2% alloy system (golden yellow); Other has the data report Soviet Union to adopt copper 85.0%, zinc 14.5% and aluminium 0.5% as imitation gold copper-base alloy.But above-mentioned alloy all can not satisfy the color and luster of imitation gold copper-base alloy and the requirement on the performance fully, and is true to nature inadequately as color and luster, and it is easy to change etc. to run into sweat stain, needs further improvement.And it is domestic, a kind of copper of the practical electrical equipment Research Institute success in ShaoXing,ZheJiang city rare gold process factory and Ministry of Light Industry Beijing, aluminium and indium rare earth alloy (being called rare gold), though its color and luster and performance all can reach requirement, but indium wherein belongs to rare metal, cost an arm and a leg, and resource is few, large-scale popularization is used certain difficulty, therefore, only be used to make jewellery at present.In addition, at present other imitation gold copper-base alloy on the domestic market all exists color and luster true to nature inadequately, and anti-atmosphere, perspiration resistance, attrition resistant poor-performing, life-time service be shortcoming such as variable color very easily.In a word, domestic and international existing imitation gold copper-base alloy can't reach color and luster and performance is all good, and low-cost again requirement.
Order of the present invention is being to provide a kind of copper alloy used for gold-like decorative purpose, and color and luster and performance are all good, and price is cheap again.
The present invention is achieved in that
A kind of copper alloy used for gold-like decorative purpose, copper removal also comprise zinc and aluminium or zinc and nickel or al and ni outward, also comprise elements such as mishmetal in addition respectively, and its prescription (in weight %) is respectively:
(1) Zn 16.0%, Al 0.5%, Ti 0.5%, Ni 0.4%, Sn 0.3%, P0.05%, mishmetal 0.05% and surplus Cu;
(2) Zn 9.0%, Ni 11.0%, Cr 0.5%, Al 0.3%, Sn 0.2%, mishmetal 0.05% and surplus Cu;
(3) Al 7.5%, Ni 1.0%, Mn 0.1%, mishmetal 0.05% and surplus Cu.
(4) Al8.0%, Ni1.5%, Mn0.25%, mishmetal 0.05% and surplus Cu.
Copper alloy used for gold-like decorative purpose of the present invention is to the further improved result of alloy ingredient on the basis of known imitation gold copper-base alloy, adopt alloy toning method to make, its color and luster beauty is true to nature, exactly like gold and karat gold, anti-atmosphere, perspiration resistance corrosion and wear resistance all are better than gold and various karat gold, life-time service can variable color, and have favorable mechanical and processing characteristics, can be processed into the sheet material of different shape, wire rod and profiled material, can be used for making spectacle frame, the pen cap, nib, watch case, the clock shell, watchband, the decorative lamp product, jewellery, artwork and various building decoration product, price only are 1/3 of existing rare gold copper-base alloy.
