Annealing the copper requires a high temperature. Copper melts at 1357Kelvin and annealing generally occurs at greater than half the melting point in degrees K; even higher temperature causes faster annealing (but not past the melting temperature, of course). Typical temperature to use is 400C or 700F. Annealing causes the structure to
How to Anneal Copper: 13 Steps (with Pictures) - wikiHow
2023年11月30日 · You can anneal any grade and thickness of copper as long as you have a flame that can transmit enough heat to the metal. The most straightforward way to anneal copper is by heating it with an oxygen acetylene torch and rapidly cooling it in water.

Annealing temperatures for various grades of cold worked copper
The temperatures used for annealing various grades of cold worked copper are given in Table 2. However, time at temperature must be controlled to avoid danger of grain growth. ... [...]
Annealing technology for copper and copper alloys
2022年10月8日 · Annealing, slow heating, control the amount of furnace, temperature lower limit, especially for thin-walled parts, to ensure uniform product performance. The temperature is controlled within ±5℃. The annealing temperature is 1.5 ~ 3h for brass and 1 ~ 3h for tin bronze, aluminum bronze and beryllium bronze.
What temperature to anneal copper? - Practical Machinist
2009年2月13日 · 750°C or a reasonable red heat. Either leave to cool or quench. Quenching leads to less oxide build up and works identically to a slow cool for copper.
Heat Treating of Copper and Copper Alloys - Total Materia
Explore the various heat treatment methods for copper and copper alloys, including homogenizing, annealing, stress relieving, and precipitation hardening. Learn how these processes can enhance the properties of copper alloys, such as strength, ductility, and hardness.
Copper Alloys and Its Heat Treatment | Metallurgy
Copper alloys, when a series of intermittent annealings are required, are usually annealed at successively lower temperatures as the metal approaches the final anneal after final cold reduction of 50-60%.
