Annealed Copper Wire
The Crazy Wire Company are best know as suppliers of top-quality bare annealed copper wires in many thicknesses. We have enormous stock levels at all times, as we use this wire to weave our woven mesh products.
0.2mm bare copper wire is a small diameter wire made of pure copper. The small size and high conductivity of 0.2mm copper wire make it suitable for a variety of applications, including electrical wiring, jewellery making, and metalwork.
In electrical applications, 0.2mm bare copper wire is often used for delicate wiring tasks, such as connecting small electrical components, or for applications where space is limited and a small wire is needed. The high conductivity of copper also makes it an ideal material for transmitting electrical signals, and for use in electrical circuits.
In jewellery making and metalwork, 0.2mm bare copper wire is often used to create delicate and intricate designs. Its malleability and ductility make it easy to shape and form into a variety of shapes and patterns.

FAQs About Copper Wire
Is Copper Toxic In Small Amounts?
Copper is an essential mineral that is required by the human body in small amounts to maintain good health. However, like many substances, copper can be toxic if consumed in large amounts.
In general, exposure to low levels of copper is not considered harmful to human health. Copper is commonly found in a variety of foods, such as meat, seafood, vegetables, and grains, and the average diet provides the body with the recommended daily amount of copper.
However, exposure to high levels of copper can cause a range of health problems, including stomach and intestinal distress, liver and kidney damage, and anemia. In severe cases, exposure to high levels of copper can cause death.
It’s important to note that the toxic effects of copper exposure are dependent on the amount, duration, and route of exposure. Ingesting large amounts of copper, either through contaminated food or water, or through supplements, can lead to toxicity. In addition, long-term exposure to low levels of copper can also result in toxicity over time.
Why Does Copper Turn Green?
Copper turns green due to a process known as oxidation, specifically due to the formation of a patina layer on the surface of the metal. When copper is exposed to air and moisture, it reacts with atmospheric carbon dioxide to form a layer of copper carbonate, also known as patina. This layer gives copper its characteristic green color and protects it from further oxidation. The exact shade of green can vary depending on the conditions in which the copper is exposed, such as the presence of pollutants, the climate, and other environmental factors. The green patina that forms on copper is not harmful and does not affect the metal’s structural integrity.
What Wire Is Best For Making Jewellery?
There are many types of wire that are suitable for making jewellery, and the best one for you will depend on your specific project and personal preferences. Here are some of the most popular types of wire used in jewellery making:
- Copper Wire: Copper wire is affordable, easily bendable, and has a warm colour that makes it a popular choice for jewellery making.
- Sterling Silver Wire: Sterling silver is a high-quality metal that is resistant to tarnish, making it a great option for jewellery that will be worn frequently.
- Gold-Filled Wire: Gold-filled wire is made by bonding a layer of gold to a base metal, resulting in a wire that looks and wears like solid gold, but at a much lower cost.
- Brass Wire: Brass wire is a yellow-coloured metal that is easy to work with and has a similar colour to gold, making it a popular choice for jewellery that requires a gold-like appearance.
- Aluminium Wire: Aluminium wire is lightweight and affordable, making it a great choice for large, statement pieces, or for jewellery that will be worn frequently.
How Do I Harden Copper Wire For Jewellery?
Hardening copper wire for jewellery making is a process that makes the wire stronger and less likely to bend or break. This can be accomplished through a few different methods, including:
- Work hardening: Work hardening involves manipulating the wire through bending, twisting, or hammering. This process rearranges the metal molecules, making the wire stronger and harder.
- Annealing: Annealing is a heating and cooling process that can be used to soften the wire, making it easier to work with. After the wire has been shaped into the desired form, it can then be re-hardened through work hardening.
- Tempering: Tempering involves heating the wire to a specific temperature and then quickly cooling it. This process hardens the wire and makes it less brittle, while also improving its resistance to breaking.
It is important to note that while these methods can make the wire stronger, they also make it more brittle, so be careful not to overwork the wire or heat it too much during the hardening process.
