Coils

Coils are wound loops or spirals of metal, typically used for their electrical conductivity, heat transfer, or magnetic properties. They are essential components in various industries, from electrical components to aerospace and medical devices.

Common Materials

Stainless Steel: Known for its corrosion resistance, stainless steel coils are widely used in construction, automotive, and food processing industries.

Nickel Alloys: Offering excellent heat resistance and corrosion resistance, nickel alloys are ideal for applications like chemical processing and aerospace.

Copper Alloys: Copper alloys boast good electrical conductivity and thermal conductivity, making them suitable for electrical components and plumbing.

Aluminum Alloys: Lightweight and strong, aluminum alloys find applications in aerospace, automotive, and construction industries.

Titanium Alloys: With a high strength-to-weight ratio and excellent corrosion resistance, titanium alloys are used in aerospace, medical implants, and chemical processing.

Manufacturing Process

Reheating: Metal stock is heated to rolling temperatures in a reheating furnace.

Scaling: The heated stock passes through a scale breaker to remove surface scale.

Rolling: The steel is rolled between large rollers to achieve the desired thickness.

Cooling: The rolled material is cooled rapidly to achieve specific properties.

Coiling: The cooled material is wound into coils for storage and transportation.

Key Features Of Coils

Conductivity: Coils can exhibit high electrical conductivity or thermal conductivity, depending on the material.
Strength and Durability: Materials like stainless steel and nickel alloys offer high strength and durability, making them suitable for demanding environments.
Corrosion Resistance: Stainless steel, nickel alloys, and titanium alloys are known for their excellent corrosion resistance, making them suitable for harsh environments.
Magnetic Properties: Some materials, such as certain types of stainless steel and nickel alloys, exhibit magnetic properties, which can be advantageous in applications like electromagnetic devices.
