Constantan - Resistance Alloy for Electrical Resistors and Heating Elements

Constantan - Resistance Alloy

Our Constantan resistance alloy is a reliable and durable material, perfect for various applications. Made of copper (Cu) and nickel (Ni), our Cu55Ni45 foil ensures optimum performance in electrical resistors and heating elements.

• Material: Cu55Ni45 - Our Constantan resistance alloy is composed of 55% copper (Cu) and 45% nickel (Ni). This unique combination of elements creates a material with exceptional electrical resistivity and thermal conductivity.
• Foil Type: 10mm disks - Our Constantan alloy is available in the form of 10mm diameter disks. This size is commonly used in applications such as electrical resistors and heating elements, providing easy integration and compatibility with existing systems.
• Thickness: 0.25mm - The Constantan foil has a thickness of 0.25mm, offering a balance between flexibility and durability. This allows for easy handling during installation or production processes while maintaining structural integrity over time.
• Surface Finish: As rolled - Our Constantan foil has an as-rolled surface finish, which is the result of the rolling process during manufacturing. This surface finish provides a slightly textured appearance, ensuring optimal adhesion and compatibility with other materials.

Constantan is often chosen for its unique properties that make it suitable for a wide range of applications:

• Electrical Resistors - Constantan's high electrical resistivity makes it an ideal choice for electrical resistors. It effectively limits the flow of electric current, providing accurate control and measurement capabilities in circuits and electronic devices.
• Heating Elements - The excellent thermal conductivity of Constantan allows for efficient heat transfer, making it a preferred material for heating elements. It ensures consistent and reliable heating performance, even in demanding industrial applications.
• Thermocouples - Constantan is commonly used as one of the wires in type E thermocouples, which are widely used for temperature measurement in various industries. Its predictable and stable temperature-resistance relationship enables precise and accurate temperature sensing.
• Strain Gauges - Constantan's balanced thermal expansion properties and high electrical resistivity make it suitable for strain gauge applications. Strain gauges made with Constantan can accurately measure and monitor mechanical strain, allowing for stress analysis and load measurement in structural components.

Our Constantan resistance alloy is manufactured using advanced production processes, ensuring high quality and consistency. The material undergoes rigorous testing and quality control measures to meet the highest industry standards. With our commitment to excellence, you can trust our Constantan foil to deliver outstanding performance and reliability in your applications.
