Abstract
The present invention relates to an electric contact material based on silver-titanium and its production technology. The production technological method is as follows: silver ingot and titanium and one or several of zinc, tungsten, copper, bismuth or nickel are put in smelting furnace to smelt and cast into ingot; or mix silver powder, titanium powder, zinc, copper, bismuth or nickel powder and press into ingot, then calcine under high temperature and cold processing, extrude into bar under high temperature and cold-process to obtain silver-titanium electric contact wire material with good processability, low price and high reilability.
Description
The present invention relates to a kind of contact material and production technique thereof based on silver-titanium.It is mainly used in makes bimetal composite rivet contact, is widely used in high power relay.
Along with the develop rapidly of automobile, aircraft industry, the consequent is more and more higher to the requirement of automobile, the employed high power relay of aircraft.The contact material of rly. often adopts Ag-Ni alloy, Ag-SnO alloy, Pd-Cu alloy etc.The Ag-Ni alloy is widely used owing to its manufacturing process maturation.But this material only is applicable to the rly. that requirement is lower, can not satisfy the requirement of the rly. that reliability is higher, carrying capacity is big.Ag SnO alloy, it has satisfied the requirement of most of rly.s to contact material, but its material in being processed into the process of contact moment hardness hard, easily split, thereby poor processability, the consumption mould is many, every mould can only be processed several thousand contacts, contact production cost height.And the contact resistance instability, work reliability is poor.Often adopt the Pd-Cu alloy as contact material to the high rly. of reliability requirement, but this material is very expensive, about 40,000 yuan of per kilograms, therefore, how developing the new contact material that processing characteristics is good, cost is low, reliability is good again, is rly. industry questions of common interest.
The object of the present invention is to provide a kind of processing characteristics is good, cost is low, reliability is high again new contact material and production technique thereof.
The object of the present invention is achieved like this: a kind of contact material based on silver-titanium, it is to contain titanium in silver matrix.
The share of titanium is the per-cent of 0.5～10.5 weight in the material of the present invention, and the share of silver is 89.5～99.5 weight percents (with respect to the gross weights of material).
Also contain a kind of of the zinc, tungsten, copper, bismuth or the nickel that account for total amount 0.1～1.5% or several in the material of the present invention.
Producing and manufacturing technique of the present invention is:
-a kind of of silver ingot, titanium and zinc, tungsten, copper, bismuth or nickel or several are placed smelting furnace melting and ingot casting; Or with silver powder, titanium valve, and powder such as zinc, tungsten, copper, bismuth or nickel a kind of or several mix and briquetting, at high temperature sintering and cold working;
-at high temperature push slivering;
-can obtain silver-titanium through drawing and electrically contact wire rod.
The temperature of the high temperature extruding of production technique of the present invention is 820 °～960 ℃.Be preferably 840 °～900 ℃.Be preferably 860 °～880 ℃
Compare with existing contact material, the present invention adds titanium and forms silver-titanium alloy material in silver matrix, and hardness is even in being processed into the process of contact, can not ftracture, thereby good processability, the consumption mould is few, and every mould can be processed a hundreds of thousands of contact, the contact production cost is low, contact resistance is stable, the work reliability height, and material price is low, its material is about 2000 yuan of per kilograms, is 1/20 of palladium-silver alloy contact material.
Fig. 1 is technological process of production figure of the present invention.
Fig. 2 is one embodiment of the invention technological process of production figure.
Below in conjunction with accompanying drawing the present invention is made a detailed description:
