The Crazy Wire Company are best know as suppliers of top quality copper wires in many thicknesses. We have enormous stock levels at all times, as we use this wire to weave our woven mesh products.
A 0.5mm bare copper wire is a thin wire with a diameter of 0.5mm and is made of pure copper without any plating or coating. Bare copper wire is a popular choice for jewelry making due to its soft, malleable nature and its high conductivity. It can be easily shaped and formed into a variety of shapes and styles, making it ideal for a wide range of jewelry-making projects.
However, bare copper wire is also relatively soft and can be prone to bending or breaking. To make it more suitable for jewellery making, you can harden the wire by following the methods I mentioned in my previous answer.

FAQs About Copper Wire
Are Copper Wires 100% Pure?
The purity of copper wire can vary, depending on the intended use and the manufacturer. Some copper wires are made of pure, electrolytic-grade copper, which is 99.9% pure or higher. These wires are typically used for electrical applications, where high conductivity and low resistance are important.
Other copper wires may be made from a less pure form of copper, or may contain other alloys to improve their strength and durability. For example, brass wire is made from a mixture of copper and zinc, while bronze wire is made from a mixture of copper and tin.
In the jewellery-making industry, pure copper wire is often used for its softness and malleability. The purity of the wire can have an impact on its colour and texture, as well as its ability to take on different patinas. If the purity of the wire is important to you, be sure to check the specifications of the wire you are purchasing, and look for products that are labelled as “pure copper” or “electrolytic-grade.”
Will Copper Wire Oxidize?
Yes, copper wire will oxidize over time, especially in the presence of moisture, air, and other environmental factors. Oxidation causes the copper to turn a greenish-blue color and can cause the wire to become brittle and weaker.
To prevent oxidation, you can coat the copper wire with a protective coating, such as clear nail polish, lacquer, or wax. You can also store the wire in a dry, airtight container when not in use. If the wire has already oxidized, you can clean it with a mild abrasive, such as baking soda and water, or a commercial copper cleaner.
It’s important to note that some patinas and tarnishes on copper can be desirable for jewellery making, and can be used to create unique and interesting effects. In these cases, it’s best to embrace the natural oxidation process, rather than trying to prevent it.
What Is Harmful Of Copper Wire?
While copper is an essential element for life and is widely used in many industries, including electronics, construction, and jewellery making, it can also be harmful if not handled properly. Here are a few potential health risks associated with copper wire:
- Skin irritation: Copper wire can cause skin irritation and rashes if it comes into direct contact with the skin for an extended period of time. This is more likely to occur in individuals with a sensitivity to copper.
- Ingestion: Ingesting copper wire can be harmful, as copper is toxic in large amounts. Children and pets are particularly susceptible to accidental ingestion, so it’s important to keep copper wire out of reach and properly stored.
- Dust inhalation: Breathing in copper dust can be harmful, as it can irritate the eyes, nose, and respiratory system. To minimize the risk of inhaling copper dust, be sure to work in a well-ventilated area and wear a mask if necessary.
- Fire hazards: Copper wire can pose a fire hazard if it becomes frayed or exposed, as it can generate sparks and ignite flammable materials.
What Happens To Copper When It Gets Wet?
When copper wire gets wet, it can experience several changes that can impact its physical properties and performance. Here are a few things that can happen when copper wire gets wet:
- Increased conductivity: Copper is a highly conductive metal, and its conductivity can increase when it is wet. This can cause the wire to carry more electrical current, which can increase the risk of electrical shock or fire.
- Corrosion: Copper can corrode when exposed to moisture, which can cause the wire to weaken and break over time. The process of corrosion can also generate copper oxide, which can be harmful if inhaled or ingested.
- Electrical resistance: The electrical resistance of copper wire can increase when it is wet, as water can act as an insulator, reducing the flow of electrical current. This can cause the wire to heat up and pose a fire hazard.
- Changes in weight: Copper wire can gain weight when it is wet, as water can be absorbed into the metal. This can impact the wire’s overall weight and affect its performance in some applications.
- Short circuits: Wet copper wire can also cause short circuits, as the water can act as a conductor and create an unintended path for the electrical current.
In general, it’s best to avoid exposing copper wire to moisture and water, as this can cause a range of issues and pose a risk to safety. If you must work with wet copper wire, be sure to take proper precautions and follow recommended safety guidelines.
