The use of tin in instrumentation
Buy tin at a bargain price from the manufacturer offers the company Elektrovek-steel. The supplier ensures the timely delivery of products to any point specified by the client.
Tin grades GOST 860−75, used in instrument making
In the manufacture of products of instrument engineering and tools are used:
- Tin of special chemical purity VHF-OO, which is supplied in pigs and rods. The metal is distinguished by high corrosion resistance, and therefore is used in the production of semiconductor technology;
- Tin of grade O1 (delivery status — blocks and pigs). It is non-toxic, has a high resistance to corrosion, and therefore is also used in various critical parts of radio equipment;
- Tin of grade O2 (GOST 18394−73). The state of delivery is a stain foil, used in the manufacture of capacitors;
In addition to pure tin, alloys of this metal are also used in instrument making.
Company Electrovek-steel, offers at affordable prices from manufacturers of tin of different brands and profiles, the chemical composition and mechanical properties of which fully meet the technical requirements of GOST 860−75 and GOST 18394−73. The supplier provides the delivery of metal to any point specified by the consumer.
The use of tin in the surface coatings of instrumentation products
Due to the low prevalence in nature, recently in the instrument-making industry, coatings based on alloys containing tin are more often used. In addition to saving scarce raw materials, the use of advanced technologies of electrodeposition of tin alloys gives the details of the devices new positive properties — increased corrosion resistance, lightness, strength.
Practical applications are alloys tin-bismuth, tin-lead, tin-zinc.
Alloys based on bismuth and tin are used as coatings for soldering parts of devices experiencing increased friction loads, to protect against corrosion phenomena, to form the necessary contacts in semiconductors.
At present, more than 20 electrolytic coatings, including tin, are actively used in instrument making. Among especially valuable properties of tin coatings are high resistance against aggressive chemical media, deformability, high soldering quality.
In addition to the aforementioned, in the instrument-making industry there are also conducted exploratory studies on working out the properties of tin alloys with cadmium, nickel, cobalt, antimony and silver.
Company Electrovek-steel offers to buy at an affordable price of the manufacturer of tin and its various alloys, which are effectively used in the instrument-making industry. The supplier guarantees prompt delivery of products to the point specified by the customer.
