Meet the Demands of Your Application

Metal sealing materials are often used in environments where extreme temperatures, high pressure, and aggressive chemicals exceed the capabilities of rubber or plastic components. When properly selected and engineered, metal seals deliver long-term durability, corrosion resistance, and structural stability.

At North Coast Seal, we work with a range of precision-machined metal materials designed to meet demanding industrial requirements. The optimal material and seal design depend on factors such as temperature range, chemical exposure, pressure levels, and mechanical loads within the application.

Our team works closely with engineers and procurement teams to understand the operating environment and develop CNC-machined metal sealing solutions tailored to those conditions.

When Metal Is the Right Choice

Metal materials are typically selected when applications require performance beyond what elastomers or plastics can provide.

Metal seals are commonly used when applications involve:

  • Extreme temperatures that degrade rubber or plastic components
  • High pressure environments requiring structural strength
  • Aggressive chemicals or corrosive fluids
  • Vacuum systems or ultra-clean environments
  • Long service life in demanding operating conditions

Because metal seals maintain dimensional stability under stress, they are frequently used in critical industrial systems where reliability is essential.When Metal Is the Right Choice

Our Metal Materials

North Coast Seal expertly engineers precision metal materials, including stainless steel, aluminum, copper, nickel alloys, titanium, brass, and Hastelloy, ensuring superior performance and longevity in a wide range of industrial applications.

Stainless Steel

One of the most widely used sealing materials due to its corrosion resistance, strength, and temperature tolerance. Stainless steel performs well across many industrial environments.

Aluminum

Lightweight and corrosion-resistant, aluminum is commonly used in applications where reduced weight and machinability are important.

Copper

Copper provides excellent thermal conductivity and is frequently used in vacuum sealing and thermal transfer applications.

Nickel Alloys

Nickel-based alloys offer strong resistance to heat and corrosion, making them suitable for demanding chemical and high-temperature environments.

Titanium

Titanium provides exceptional strength-to-weight ratio and corrosion resistance, particularly in aerospace and marine environments.

Brass

Brass offers good machinability and corrosion resistance, making it suitable for various industrial and fluid-handling components.

Hastelloy

Hastelloy alloys provide outstanding resistance to aggressive chemicals and extreme temperatures, making them ideal for highly corrosive processing environments.

    FAQs About Metal Materials

    Metal seals are typically used in high-temperature, high-pressure, or chemically aggressive environments where elastomer or plastic materials may degrade.

    Nitrile (NBR) and fluorocarbon (FKM) materials are commonly used in environments involving oils, fuels, and hydraulic fluids due to their strong chemical resistance.

    High-performance plastics such as PEEK, PPS, and PEI are designed to maintain mechanical strength and stability in elevated temperatures.

    PTFE provides exceptional chemical resistance and low friction. PEEK offers high mechanical strength and temperature resistance, while PPS balances chemical resistance with dimensional stability.

    Yes. Many engineering plastics can be machined or injection molded to precise tolerances, making them suitable for complex industrial components.
