ProAlloy zinc couplers from Powermite

Plugs, sockets and couplers which facilitate the connection of electrical cables to mobile mining equipment are high-theft risk components and
the cost of replacing these critical parts is aggravated by downtime and subsequent production losses.
“Couplers traditionally manufactured from brass, leaded gun metal or stainless steel carry a high theft risk due to their extremely high weight-to-value ratio,” says Donovan Marks, marketing director of Powermite. “Following a three-year research and development programme, we came up with a perfect solution for industry in the form of a coupler that is manufactured from our patented non-theft ProAlloy material to specification.”
These ProAlloy couplers are not only 33% lighter in weight compared to their brass equivalents but are lighter on the pocket too. The ProAlloy material is comprised of a zinc, copper and aluminium mix which holds no resale value, thus earning the name non-theft material. “The fact that the mix is contaminated by the aluminium reduces the value from approximately R35/kg to R6/kg and thus cannot be sold for scrap,” explains Marks. He adds that they further assist customers by buying back the metal at R15/kg, effectively closing the loop.
“Due to the fact that it is a unique patented alloy, material movement can be controlled between manufacturer, supplier and end-user,” adds Marks. He further notes that the ProAlloy coupler demonstrates material integrity, retains its machinability and remains completely malleable. The zinc product has undergone stringent corrosion tests conducted by Mintek against brass in mining water and results showed that there is no corrosion affect.
