Copper is the perfect conduit for heat and electricity, though balls or spheres made of copper are not recommended to the occasions or situations where they are exposed to corrosive liquids or appliances under high stress. These balls or spheres are , however, soft and sensitive to corrosion from various materials.
Copper balls or spheres of Foshan Dongyuan Company range from 6mm to 300mm, with 0.8mm in thickness. The most sought-for coppers fall under the category of accessories of clothings, footwear and jewelry. They are also of excellent quality and superb craftmanship. Welding is employed in the copper balls without a noticeable seam and could also be applied in many ways. And we believe they could also be employed for many fruitful uses.
Our copper balls come with no holes but could be customer-orientated, that is to say, we could add a hole or holes to your balls as you want. Drilling with small holes is free of charge and please rest assured that everything of the copper balls will come out as perfect as possible.
The world's copper production is still rising. This basically means that more and more copper ends up in the environment. Rivers are depositing sludge on their banks that is contaminated with copper, due to the disposal of copper-containing wastewater. Copper enters the air, mainly through release during the combustion of fossil fuels. Copper in air will remain there for an eminent period of time, before it settles when it starts to rain. It will then end up mainly in soils. As a result soils may also contain large quantities of copper after copper from the air has settled.
Copper can be released into the environment by both natural sources and human activities. Examples of natural sources are wind-blown dust, decaying vegetation, forest fires and sea spray. A few examples of human activities that contribute to copper release have already been named. Other examples are mining, metal production, wood production and phosphate fertilizer production.
Because copper is released both naturally and through human activity it is very widespread in the environment. Copper is often found near mines, industrial settings, landfills and waste disposals.
Most copper compounds will settle and be bound to either water sediment or soil particles. Soluble copper compounds form the largest threat to human health. Usually water-soluble copper compounds occur in the environment after release through application in agriculture.
Q: Do you have a stainless steel ball of 25mm?
A: As for those standard sizes, we always have stock.
Q: Do you have a 1000mm ball ? How long can I get it?
A: This ball falls into a category of big size sphere, so it takes some time in manufacturing and delivery.But rest assured you could get it as soon as possible.
