    Hello Mr. Kumar.K Senthil,

    The first thing we recommend is that you purchase the Nonferrous Wire Handbook Volume 3 from the WAI store:

    portal.wirenet.org/eweb/DynamicPage.aspx...DA-90A3-CDFBA601F1EE

    and the Nonferrous Wiredrawing Coolants Booklet from the WAI Store and start reading.


    portal.wirenet.org/eweb/DynamicPage.aspx...20-9CCC-ABFDE6B395F7

    Moreover we recommend you contact your wire drawing lubricant supplier/ manufacturer and obtain all the technical information you can obtain.

    Hello Mr. Suman Roy,

    Sometimes, when you are running your machine very slow, you get chattering on the capstans inside the machine. If this is happening, there is indeed the opportunity for inclusion type wire breaks due wire shock and reduced cross-section area by virtue of the inclusions.

    There have been a number of threads on copper wire discoloration in the Forums.

    We therefore refer you to the following threads over the past five or six years.

    www.wirenet.org/wai-forums/8-nonferrous/...opper-wire-tarnished
    www.wirenet.org/wai-forums/5-electrical/...-tarnished-after-pvc

    Copper(I) Oxide, Cuprous Oxide, Cuprite or Red Copper Oxide (CuO2)
    Cuprous Oxide can easily coat the conductor and it is a brownish-red solid. The chemical formula is CuO2 meaning two oxygen atoms combine with one copper atom. (Cu + O2 = CuO2). On copper wire, you can see the cuprous oxide layer in full color as various shades of reds, oranges, pinks, and purples if the copper has been heated too high (Above about 200 degrees Celsius (392 Fahrenheit) and exposed to oxygen. Moreover keep in mind that when copper is hot, it quickly oxidizes (corrodes or rusts) and this is nothing more than a simple chemical reaction with oxygen.

    On the other hand:
    Copper(II) Oxide, Cupric Oxide (CuO)
    Cupric Oxide can as well easily coat the conductor and it is a black solid. It can be formed by heating copper in air at around 300 - 800°C:

    This is a good starting spot for your issues.

    We are one of the leading manufacture of Building wires and cable in India.
    We want to test the ambient air quality for our factory premises for the purpose of copper reacts with the open air wire surface color ( It may be blackish Or Reddish) .
    Please advise the any test to be conduct through third party environment lab and any particular elements check for precaution for copper wire drawing manufacturing.
