Cr10Ni90 Constantan Wire Resistance for Harsh Environments

Cr10Ni90 alloy wire has good high-temperature strength and creep resistance, giving it broad application prospects in high-temperature applications. This alloy wire is often used in the manufacture of high-temperature structural components in gas turbines, aerospace engines and nuclear energy. Its high temperature stability and antioxidant properties allow it to withstand extreme working conditions.

Application:

1. Heating elements: Cr10Ni90 alloy wire is often used as a material for heating elements, such as electric furnaces, heating wires, furnace wires and heaters. Due to its high temperature stability and good resistance characteristics, it can provide stable heating effect in high temperature environment.

2. Resistors: Because Cr10Ni90 alloy wire has high resistance and temperature coefficient, it is widely used in the manufacture of resistors. Resistors are commonly used in circuits for functions such as current limiting, voltage dividing, and resistance adjustment.

3. Thermocouple: Cr10Ni90 alloy wire, as the temperature-sensitive part of the thermocouple, can convert temperature changes into voltage signals for temperature measurement and control. Thermocouples are widely used in industrial control, heat treatment, laboratory measurement and other fields.

4. Chemical industry: Because Cr10Ni90 alloy wire has good corrosion resistance, it is often used in corrosive media sensors, valves, pipelines and other equipment in the chemical industry. It maintains stability and reliability in harsh chemical environments.

5. Hot air drying: Cr10Ni90 alloy wire can be used as a heating element in hot air drying equipment to heat and dry materials, such as in food processing, textile and paper making industries.

Packaging:

Sturdy cardboard boxes are used for packaging NiCr Alloy.

Each box has dimensions of approximately 26 cm (length) x 26 cm (width) x 30 cm (height).

The boxes are designed to provide protection to the contents during transportation.

A plastic wrap is used to seal the boxes, ensuring that the contents are shielded from dust and moisture.

The boxes are labeled with important information, including the product name, quantity, and destination.

Shipping:

The shipping method for NiCr Alloy depends on the customer's requirements.

Two options are mentioned: airmail and sea freight.

Airmail is a faster but relatively more expensive shipping option, suitable for customers who require quick delivery.

Sea freight is a cost-effective shipping option that is commonly used for transporting bulk quantities of goods over longer distances.

It's important to note that specific packaging and shipping processes may vary depending on the manufacturer or supplier. The information provided here offers a general understanding of how NiCr Alloy is typically packaged and shipped.
