Alumel products for U.S. buyers
Alumel is a nickel-base thermocouple alloy commonly identified as the negative leg in a Chromel-Alumel Type K pair. The alloy name alone is not a complete purchase specification. The quotation request should identify the required form, size, condition, calibration or tolerance class and applicable drawing or standard.
Wire, strip and bar requirements
Sourcing can be reviewed for wire, strip, ribbon and bar, subject to the requested grade, dimensions and quantity. For wire, state diameter, spool or straight length and any calibration requirement. For strip or ribbon, state thickness, width, coil or cut length, edge condition and tolerance.

Pairing and material selection
For a Type K system, identify the complete thermocouple or extension-wire requirement rather than selecting material from nominal chemistry alone. Alumel, Nial and other nickel-base negative-leg materials may follow different purchaser specifications. Any substitution requires buyer or engineering approval.
