1. CU vs. TCU: What Are They?

CU (Copper-clad steel) is a composite material that features a core of steel, clad or coated with a layer of copper. TCU (Thermocouple) is a temperature sensor composed of two dissimilar metals joined at one end. This junction produces a voltage proportional to the temperature, allowing for accurate temperature measurements. Understanding the basic definition of each material is the first step in understanding their differences.

1.1. CU - Copper-Clad Steel: Composition and Properties

CU is known for its combination of the strength of steel and the conductivity and corrosion resistance of copper. The copper cladding provides excellent electrical conductivity and resistance to corrosion, while the steel core offers high tensile strength and mechanical stability. Common applications include grounding rods, electrical conductors, and communication cables. CU is often chosen when a balance of cost, strength, and conductivity is required. — Decoding `confint()` Output: Your Guide To Confidence Intervals

1.2. TCU - Thermocouples: Composition and Properties

Thermocouples are made from two different metal wires joined at a sensing point. This junction creates a voltage (the Seebeck effect) that corresponds to temperature changes. The choice of metal pairs determines the temperature range and accuracy. Thermocouples are widely used in industrial and scientific applications for measuring temperature in harsh environments, offering a wide temperature range and robustness.
