the Alloys, so the main binder as copper belong to the category of non-ferrous metals. Made of them resulting parts can be distinguished by the following technical parameters:
- Elasticity and plasticity.
- Acceptable resistance to corrosion and chemically active substances.
- Low specific gravity.
- Accessible cost for the consumer (customer).
- Like "Compressing" connecting or sealing site when creating a certain pressure force on the outer plane of the surface (nut, connecting a design element).
- to Withstand high and low temperatures without any structural deformations (cracks, tears).
- to feel Confident in a chemically active environment.
- Annealing – heating to a temperature of 700 degrees and slow cooling "in the air".
- Passivation – a costly but effective way of anti-corrosion surface treatment copper alloys.
Which allows their use in various fields as a sealing and connecting components. In contrast to the technical rubber and plastic materials, for example, the classic, made according to GOST copper sealing washerable:
It is the latter ability is the main criterion for choosing copper washers as sealing element in machine engineering, production of hydraulic equipment as well as the aviation industry. Sufficient strength copper alloy allows you to use a washer for fixation of the packing in the various units operating in conditions of high vibration, temperature changes with the use of fuels and lubricants.
Additional anti-corrosion treatment
Copper in their physical molecular properties is subject to oxidation at interaction with oxygen. This is manifest in the formation on the surface of products from copper alloy characteristic green patina. To exclude the manifestation of such processes copper washers are further processed:
to Get more information about the types and technical characteristics of the copper sealing washers, you can use the official website of the company carbon Group engaged in their delivery and implementation in the online format. Presented in the resource directory of the product meet the stated dimensional parameters and standards of GOST.
