Bimetallic Screw Barrels

Bimetallic Screw Barrels

A bimetallic screw barrel is a screw used in hydraulics. The materials used to make it include bi-metal alloys, like HASTELLOY. The screw can be of different diameters. The diameter of the screw depends on the product. The internal and external diameters can be 14mm to 300mm. The outer diameter of the barrel depends on the application. ULTIMET(tm) and HASTELLOY(r) are registered trademarks of Haynes International USA. The Hoganas group of Germany is also a leading supplier of Bimetallic Screw Barrels.

A bimetallic screw barrel is often made from a high-performance steel alloy. It is highly resistant to corrosion and wear and can even withstand up to 50% glass fiber in some applications. It is possible to choose between a nitrided steel screw barrel and a bimetallic screw barrel. The former costs 1.5-2 times more than the latter. The advantages of a bimetallic barrel are that the product is more durable, is less expensive, and is more versatile.

Another major advantage of a bimetallic screw barrel is its ability to handle a wide range of materials. Recycled plastic is used in many different applications, including drip irrigation and plain plastic pipes. However, these plastics contain particulates, impurities, and plastic additives that can cause additional wear and corrosion on the screw barrel. The use of a recycled material may be harmful to the screws, especially those used in the production of electrical components.

As a result, single-steel screws will wear out easily. In response to this, industry has developed several grades of performing steel alloys. However, these screw barrels are expensive. A superalloy screw barrel costs up to six or eight times as much as a nitrided steel screw barrel. Furthermore, milling these superalloys takes more time than nitrided steel. By contrast, a bimetallic screw barrel costs 1.5-2 times as much as a nitred steel equivalent. Regardless of its cost, a bimetallic screw barrel has a life span that is two to five times longer than a single-metal one.

A bimetallic screw barrel is made of two different types of metal: a base screw, which is made of one metal, and a second, stronger screw that is made of another metal. The second type is a metal composite. A bimetallic screw barrel can handle more than 20 different types of metal, including performance alloys. A bimetallic barrel is often used in construction and manufacturing processes, and can also be reused.

A bimetallic screw barrel is used in extrusion machines. It is made up of a screw and a second, stronger metal. The barrel is usually coated with a material that is abrasion-resistant. Its dual-material screws have better abrasion and higher corrosion resistance, and can be used in a wide variety of applications. These are all examples of the uses of a bimetallic screw.
