Can be heat-treated for additional durability and performance.
Disadvantages:
Prone to corrosion if not coated or treated.
More expensive than standard carbon steel.
Brass
Description: Brass is a copper-zinc alloy known for its excellent corrosion resistance, electrical conductivity, and aesthetic appearance. It is often used in environments where rust prevention and conductivity are essential.
Model: H60、H62、H65、C3604、H70、H90、T1、H59；tin bronze、Phosphor bronze、Silicon bronze、Aluminum bronze、Manganese bronze etc
Applications:
Electrical Industry: Brass fasteners are commonly used in electrical connectors and components because of their excellent conductivity.
Plumbing: Brass is used in pipes and fittings due to its resistance to water corrosion.
Decorative Applications: The gold-like finish of brass makes it ideal for decorative fasteners in furniture, lighting fixtures, and other aesthetic components.
Advantages:
Excellent corrosion resistance, especially in water-based environments.
Non-magnetic and highly conductive.
Aesthetic appearance suitable for decorative purposes.
Disadvantages:
Lower tensile strength compared to steel.
Higher cost due to the price of copper.
Titanium
Description: Titanium is a high-performance metal known for its excellent strength-to-weight ratio, corrosion resistance, and ability to withstand extreme temperatures. It is much lighter than steel but stronger than aluminum, making it ideal for specialized applications.
Model: TC4、Ti-6Al-4V 、TC4ELI，TA2，GR5
Applications:
Aerospace: Used in aircraft, spacecraft, and missiles where strength, low weight, and high-temperature resistance are crucial.
Medical: Titanium is biocompatible, making it suitable for implants, surgical tools, and dental components.
Marine: Titanium fasteners are used in saltwater environments due to their extreme corrosion resistance.
Advantages:
Outstanding strength-to-weight ratio.
High resistance to corrosion, even in aggressive environments like seawater.
Can withstand high temperatures without losing strength.
Disadvantages:
Extremely expensive compared to most other metals.
More difficult to machine and fabricate due to its hardness.
Nylon and Other Plastics
Description: Nylon fasteners and other plastic materials are non-metallic and are commonly used for applications where lightweight, corrosion resistance, and electrical insulation are important. While not as strong as metal fasteners, plastics provide unique advantages in certain environments.bus leo.
Applications:
Electronics: Nylon fasteners are used in electronic enclosures and components because they are non-conductive and provide electrical insulation.
Automotive: Lightweight plastic fasteners are used in non-structural parts like dashboards and interior trim components.
Medical Devices: Non-reactive and lightweight, plastic fasteners are often used in disposable medical devices and equipment.
Advantages:
