What are the main uses of bimetal screws?

A bimetal screw is a new type of connector that consists of two metals of different materials, usually steel and aluminum. This type of connector is formed by pressing the two metals together. They are widely used in air conditioning, refrigeration equipment, machinery manufacturing and other fields. The following are the main uses of bimetal screws.

Thermal insulation

One of the main uses of bimetal screws is to provide thermal insulation in refrigeration equipment. This type of screw allows for the safe connection of coolant piping without causing heat transfer. Since the two materials of the bimetallic screw have different coefficients of expansion, they do not cause heat transfer even when undergoing multiple temperature changes. This makes them ideal for use in the following equipment:

-Refrigeration equipment

-Cooling towers

-Heat exchangers

Corrosion protection

Bimetallic screws can also be used for corrosion protection. They are constructed to make connections in corrosive environments and to protect the connections from corrosion. Mono-material bolts and nuts are susceptible to corrosion by elements that are harmful to them.

Since the outer layer of bimetallic screws is usually aluminum, they can be treated with surface treatments such as chemical oxidation or anodizing to improve their corrosion resistance. Not only do these methods provide additional protection for bimetallic screws, but they can also be given a variety of colors and textures.

Strength and lightness

Bimetallic screws are made up of two different materials, which provides them with substantial material strength and lightweighting. This construction makes bimetallic screws easier to handle and install during lengthy manufacturing processes, and provides effective connection forces and weight distribution. Bimetal screws can also be used in the following equipment:

-Food processing and packaging industries

-Cosmetic manufacturing

-Automotive manufacturing and repair

Overall, bimetallic screws are an important part of a range of products that can be used as connectors in different manufacturing industries. Their special design and construction gives them an advantage in providing strength, light weight, thermal insulation and corrosion protection. Their benefits are evident and hence have a wide range of applications in specific fields of application.
