It is said that copper powder is widely used in diamond tooling process. Is this verdict correct? What are the benefits of using this copper powder in the production of tools of diamonds?
Yes! This statement is correct that copper powder is also used in the diamond tooling process. The fact about copper is that it has been used widely as a binding material for the tools that are generally the super hard cutting tools.or materials. The main reason behind the use of this spherical copper powder for the diamond tools is that the presence of this copper powder basically lowers the sintering temperature of the matrix. Because of this lowering of the temperature, it becomes easy for the formation of alloy with other metals. Apart from this fact, the copper powder has also been widely used because of its benefit to the overall sharpness and efficiency of the blades that are used to cut hard materials. The presence of copper powder enhanced the cutting ability of the tool.
How is the use of spherical copper powder beneficial in anti-fouling paints? Do you have copper powder available that can be used in anti-fouling paints?
The fact behind this is that copper powder is indeed one of the most effective biocide that is also environment friendly. Because of the biocidal properties of copper powder, it is widely used in marine paints. Such paints having copper powder are referred to as the anti-fouling paints. The main purpose of such paints is to simply make the specific surface inhabitable for the living organisms and this is done by the biocidal properties of copper powder.
The copper powder that is required to be used in anti-fouling paints should be spherical powder, this is because it is distributed in an easy way across the surface. We manufacture quite fine spherrical copper powder that can surely be used in anti-fouling paints and will definitely provide amazing results.
For how long, will this spherical copper powder be effective in anti-fouling paints or marine paints? How long will this copper provide its biocidal properties?
The lasting and effectiveness of this in anti-fouling applications basically depends on the ways in which it is used. For instance, if an anti-fouling paint is applied directly on the metal surface, then it will result in corrosion because the copper present in the paint will react with the metal of the surface on which the paint is being applied. Another important thing is that you can improve the functioning of anti-fouling paint by polishing the surface on which this paint is applied. This is because after sometime, the anti-fouling paint becomes dry, but the polishing of the surface will expose more copper present in the paint and will ultimately benefit and improve the anti-fouling properties of the paint.
I work in an electronic industry and I was wondering how I can make use of the product in my field?
Being in an electronics related field, you can definitely make use of the product. Copper powder has extraordinary electrical and heat conductivity.

Pure copper powder offers excellent conductivity to electricity and therefore, it can be used in the electronics industry as well. Its general use would include the formation of electronic circuits.
What would happen when I will heat spherical copper powder in a china dish? Why does it change its color?
When you will heat the this in a dish, then you will observe that a black substance is formed on the surface. This formation of black substance on the surface is called as the surface oxidation. The phenomenon behind this formation of black substance is that when copper is heated, it reacts with the atmospheric oxygen. A reaction takes place between the copper powder and the oxygen present in the atmosphere. This reaction results in the formation of copper II oxide and this is actually the black substance that is formed. Therefore, the color is changed because of the oxidation that takes place.
Can this spherical copper powder cause any harm or damage when used without precautions or is it safe to use it even without precautionary measures?
