Fastener Wikipedia-How to choose Fastener Material

Fastener Material

Fasteners are manufactured in a wide range of materials . Include steel, stainless steel, aluminum, brass, titanium and nylon. Gennerly Speaking , steel and stainless steel is popular .

 

Fastener Material Type and Characteristics

 

Steel: Most popular, strong, durable, and cheap. With different hardness.

Stainless Steel: superior corrosion resistance,durability 

Aluminum: Lightweight, soft, corrosion-resistant, and non-magnetic.

Brass/Bronze: Excellent corrosion resistance for aquatic applications; brass is used for good appearance.

Titanium: High strength-to-weight ratio, high heat resistance, and excellent corrosion resistance.

Non-Metal/Polymers: Nylon is common for being lightweight and an insulator.

 

How to choose the material of Fastener produce：

 

Choosing the right fastener material requires evaluating the application's corrosion resistance, strength (load), temperature range, and cost.

 

• Environmental Conditions (Corrosion Resistance):
  • Stainless Steel (300 Series/A2/A4): Best for outdoor, marine, or chemical environments due to high rust resistance.
  • Coated/Plated Steel: Zinc-plated, galvanized, or yellow zinc-plated steel offers good rust protection at a lower cost.
  • Brass/Silicon Bronze: Excellent for decorative, marine, or electrical applications.
•  
• Strength and Load Requirements:
  • Carbon Steel: Standard for most industrial applications; offering high tensile strength.
  • Alloy Steel: Heat-treated for high-strength, heavy-duty, or high-torque applications.
  • Grade 8/Property Class 10.9/12.9: Used for maximum tensile strength, though often less corrosion-resistant.
• Temperature Considerations:
  • High-Temperature Alloys: Required for automotive, aerospace, or furnace applications where standard metals weaken
• Material Compatibility (Galvanic Corrosion):
  • Avoid coupling dissimilar metals (e.g., stainless steel in aluminium) in wet
  • environments to prevent rapid corrosion.
• Application Type: 
  • Permanent/High Stress: Use steel or alloy fasteners.
  • Temporary/Low Stress: Plastic or nylon may be suitable.
