How to choose raw materials for fasteners

Release time:


When selecting raw materials for fasteners, the following aspects need to be considered:

Mechanical performance: Fasteners need to have certain mechanical properties, such as strength, toughness, wear resistance, etc. Select appropriate materials and processes based on usage requirements and stress conditions to meet mechanical performance requirements.

Corrosion resistance: In some corrosive environments, fasteners are prone to corrosion. Therefore, choosing materials with good corrosion resistance, such as stainless steel, copper, etc., can improve the service life of fasteners.

High temperature resistance: For fasteners that need to be used in high-temperature environments, materials with good high-temperature performance should be selected, such as nickel based alloys, titanium alloys, etc.

Weight: For some situations that require lightweight, materials with lower density should be selected, such as aluminum alloys, titanium alloys, etc.

Cost: Material cost is one of the important factors to consider when selecting raw materials for fasteners. Choosing materials with high cost-effectiveness based on usage requirements and budget can reduce costs while ensuring performance and functionality.
