Product Description

Custom Precision Machined Alumel Pins for Connectors Electrode Use

Alumel is a magnetic alloy, it consists of approximately Nickel (95%), Manganese (2%), Aluminum (2%), and Silicon (1%), leading to good electrical resistivity and thermal conductivity. In addition to thermocouples, alumel is used for thermocouple extension wire. In thermocouples, this alumel alloy is used as negative conductor to fabricate type K thermocouples with chromel.

Alumel Conductor Pin Applications:

Our machined alumel pins are used as negative conductors in Type K thermocouples. Chromel–alumel thermocouples (type K) are a widely used general purpose device with a measurement sensitivity of 41 μV/°C. Their output characteristic is particularly linear over the temperature range between 700 °C and 1200 °C and this is therefore their main application, although their full measurement range is −200 °C to +1300 °C. Like chromel–constantan devices, they are suitable for oxidizing atmospheres but not for reducing ones unless protected by a sheath. Their measurement inaccuracy is ±0.75%.

Seehao company gets specialized experience, extensive knowledge, and advanced CNC equipments to machine a wide array of high nickel, including various alumel alloys. Our custom design and manufacturing services means you receive a unique machining solution to your complex terminals and connectors.

We can design and manufacture various machined alumel conductors, also known as machined chromel pin, for use in high quality thermocouples, feedthrough, and connectors. We can provide one –stop services for your wanted machined component for your thermocouple and connectors assembly.

Whether your interconnect application is for development, test, or volume production, we will be willing to provide satisfied
alumel machining service for you. We always use the high grade certified alumel alloy with strict quality control, this will
ensure the quality of finished alumel terminal pins.
