- Mild steel: Common material for exhaust pipes due to its affordability and durability. It contains a small percentage of carbon and is corrosion-resistant.
- Stainless steel: Provides better corrosion resistance and longevity compared to mild steel. Some stainless steel alloys used in exhaust systems are:
- 409 stainless steel: Found in budget-friendly exhaust systems due to its cost-effectiveness.
- 304 stainless steel: Widely used for exhaust systems, combining strength, durability, and corrosion resistance.
- 444 stainless steel: High-performance alloy known for its heat resistance and strength, often used in racing applications.
Brake Pipes:
- Copper-nickel alloy (Cunifer): Commonly used material for brake pipes due to its excellent corrosion resistance, even in harsh environments. It is flexible and relatively easy to work with.
- Stainless steel: Also utilized in brake pipes due to its resistance to corrosion and heat. However, it is less malleable compared to copper-nickel alloys.
Fuel Pipes:
- Steel: Steel pipes, often coated for added protection, are used for fuel lines. They provide strength and resistance to damage from vibrations and impacts.
- Aluminum: Some fuel lines may use aluminum due to its lightweight and corrosion-resistant properties. However, it is less commonly used compared to steel.
- Nylon or rubber: Flexible fuel lines made of nylon or rubber can also be used in certain areas to handle changes in angles or engine movement.
