Q: What makes up a K-Type Thermocouple?
A: Al-Cr, Alumel and Chromel 1
Q: What is Alumel?
A: Alumel is an alloy of 95% nickel, 2% aluminum, 2% manganese, and 1% silicon
Q: What is the process of alloying Alumel?
A: Research ongoing
Q: What is Chromel?
A: Chromel is an alloy of 90% nickel, 10% chromium
Q: What is the process of alloying Chromel?
A: Research ongoing
Q: Which Chromel is typically used in K-Types? (A,C, or R?)
A: Research ongoing
Q: Which "leg" (negative/positive) is which?
A: The positive legs is Chromel and the negative leg is Alumel 2
Q: How are the two wires connected? (Soldered, welded, braised?)
A: Would seem to be welded. I'm thinking of trying to use a battery terminal spot welder
