Material selectionWhat Specialty Materials Work Best for Pressure Instrument Components?

  • Nickel and High Temperature Alloys
  • Stainless Steel and Specialty Steel
  • Aluminum Alloys
  • Copper Alloys

Nickel and High Temperature Alloys

Nickel steel alloys are extremely popular for Pressure Transducer housings and fittings. It is designed for critical applications where extreme conditions are required. This demand is due to its increased hardness, tensile strength, and elastic limit, all without reduced ductility. It also maintains strength at elevated temperatures as high as 1,050˚C to 1,200˚C. The nickel-based super alloys Inconel and Hastelloy are also used extensively.

Below are some of the grades in stock:
Nickel-Chromium Alloys – Inconel®
Inconel 600
Inconel 617
Inconel 625
Inconel 718

Nickel-Molybdenum-Chromium Alloys – Hastelloy®
Hastelloy C276

Stainless Steel and Specialty Steel 

Stainless steel alloys have found increasing usage in Pressure Transducers, Transmitters and Switches that require great strength but can handle the increased weight. The high corrosion and temperature resistance found in stainless steel make it suitable for a range of fittings used on heavy duty pressure transducer and vacuum switch.

Below are some of the grades in stock:
AISI 303
AISI 304
AISI 316
AISI 630

Aluminum Alloys

There is a great deal of aluminum alloys for Pressure sensing applications. Most aluminum alloys offer high weight to strength rations, corrosion resistance, formability, and favorable pricing.

Below are some of the grades in stock:
Aluminum 2011
Aluminum 4032
Aluminum 6061
Aluminum 6063
Aluminum 7075-T7651

Copper Alloys

With copper’s outstanding conductivity, it is the metal of choice for high over-voltage situations, and ensures that the device is compliant with industry standards. It is widely used on environmental solution for indoor applications such as building automation and HVAC systems in residential and office buildings. It is widely used for temperature sensors.

Below are some of the grades in stock:
