Abstract

Golden darkening proof copper base alloy for docoration is by aluminium, tin, copper and rare earth etc. are elementary composition, this alloy is a kind of golden non-corrosive metal, has good decoration effect, golden gloss can not fade because of wearing and tearing, after adopting technologies such as founding and thermomechanical treatment to handle, make alloy have good thermal distortion plasticity, can be processed into sheet material, bar and wire rod, improved the workability of this alloy, the watch case made from this alloy, ring, souvenir badge and the smart industrial art statue of casting type, golden gloss is equivalent to the 18K gold, extremely attractive in appearance, obtain splendid decorative effect.

Description

The invention belongs to the manufacturing processing technology of non-ferrous metal and alloy.
Golden darkening proof copper base alloy for docoration is a kind of golden non-corrosive metal that does not have noble element, has noticeable decorating feature.The golden gloss of this alloy is different from plating, spraying plating one class surface metal gloss.Electroplate coating gloss such as golden frame, wristwatch case and be unable to undergo to wear and tear, will fade after use for some time.And that the color and luster of this alloy can keep is the same outside and inside, grinds and more demonstrate the golden yellow color of alloy institute inherent.Manufactured wristwatch case, ring, souvenir badge and the smart industrial art statue of casting type, bright and glittering, golden light flicker, quite 18K gold.
Nineteen eighty-two Germany patent DE3116125 is open, contains 5-7%Sn, and the copper alloy of 1-3%Al is through casting calendering and stamped coin.This alloy has than Cu-Al-Ni alloy better dark performance of resistance in various media.(ACC-NO:8202634J/08248,PRIORITY:810423 DE116125,IPC-CODE:A44CO2100 C22COO901)。Germany patent DE3235833 in 1984 is open, contains 1~7%Sn, 1~7%Al copper alloy is used to make clock and watch, jewellery, trophy etc.(ACC-NO 84083057/08414 PRIORITY:820928DE235833,IPC-CODE C22COO902 C23COO500)。
But the alloy cast ingot by above-mentioned alloy component range founding has very poor thermoplasticity.Add in hot rolling or forge hot and seriously to ftracture man-hour, can not process and become a useful person.
The objective of the invention is to: (1) adds a small amount of rare earth at the shortcoming of the thermoplasticity difference of the Cu-Al-Sn alloy of existing patent in alloy, make alloy have good thermal distortion plasticity, makes alloy can be processed into sheet material, bar and wire rod.Improve the workability of alloy.(2) handle the best solidity to corrosion of acquisition with solutionizing.(3) with deformation heat treatment method hardness of alloy and intensity can be adjusted in a big way, and keep alloy gloss constant.
Ultimate principle of the present invention is as follows: (1) imitative gold contain golden composition be 2-7%Al, 1-5%Sn,<1% rare earth, all the other are copper.(2) founding is as follows, melts at high frequency induction furnace.Electrolytic copper melts the back and adds fine aluminium and pure tin in crucible, fully stir, and after the phosphor-copper deoxidation, adds the aluminium-rare-earth master alloy, immediately cast.Teeming temperature is 1050-1150 ℃ and adopts soda and borax to make flux.(3) homogenizing and hot rolling (forging), ingot casting took out hot rolling (forging) after 800-850 ℃ of heat tracing 5-7 hour after surfacing cut processing.Finish to gauge (forging) temperature is 780-750 ℃.Heating for multiple times is recovered plasticity in the operation of rolling.(4) recrystallization annealing be 600-670 ℃ the insulation 0.5-1.5 hour after the cold or air cooling of stove.Chilling is realized the solutionizing processing in this temperature heating back water.(5) thermomechanical treatment comprises: the hardness 75-80HV of the attitude of 1. quenching, and make hardness increase to 190-200HV through 50% cold deformation, through 300 ℃ of heating in 0.5 hour, hardness increases to 230-235HV; 2. hot rolling attitude hardness after 50% cold deformation reaches 250-260HV, and hardness increases to 290-300HV after 300 ℃ of heating in 0.5 hour.
This alloy can be made into article such as ornament, workmanship, tourist souvenir, picture frame, spectacle frame, commemorative coin.The ratio of materials cost in cost is very little, will have very big economic benefit.Be used to make vessel such as wristwatch case, clock and watch decoration, door knob door bolt, hotel decoration, light fixture pendent lamp, commodity are updated, improve competitiveness.Product beautifies the people's material life and cultural life, and the wide society demand will be arranged.Replace gold-plated goods with this alloy, can save a large amount of gold.
Embodiment:
No. 207 alloy has 6%Al, 2.5%Sn, 0.08%Ce.15 kilograms of high-frequency induction foundings pour into 55 millimeters rods of φ, and forge hot Cheng Fang is through being hot-rolled down to 6.5 millimeters plates, 670 ℃ of annealing in 0.5 hour.Heat and be washed into watch case.The mechanical workout moulding.610 ℃ of solutionizing in 0.5 hour are handled.Mechanical polishing is also washed dried making an uproar, and color and luster reaches 18K.The 5%NaCl aqueous solution, 25 ℃ of 24 hours salt-fog tests are qualified.
This alloy is as follows with tension test and its mechanical property of determination of hardness test:
σb Kg/mm 2δs% φ% HV
Hot rolling attitude 42.2 47.3 49.4 122
Cold rolling attitude 79.6 9.4 42.2 240
Alloy strength is moderate, and plasticity is good, has tangible work hardening capacity.
Alloy is made wristwatch case and had golden color, and is gorgeous attractive in appearance.Can be made into ring, souvenir badge, statue etc.
