    FAQ

     

    What is your lead time?

     

    -- Our general lead time is 10-15 days but may extend during peak periods.

     

     

    Is a deposit required?

     

    --It depends on the price of the purchase. If it is over 10,000 o, then a deposit of 50% of the total sum is required in advance, and the rest could be paid before the products are finished. 

     

     

    If I re-size your designs, is there a price change? 

     

    --In most cases, varying the design will result in minimal variations in price. Customising would mean the cost of creating a new template, changes in laser cutting time, and re-formatting our machines usually contributes to a re-size fee.

    Product Description

     

    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.

     

    Copper is a reddish coloured metal which is malleable and ductile. It has excellent thermal and electrical conductivities and good corrosion resistance. It is found in sulphide ores and as carbonate, arsenide and chloride (abundance in the Earth's crust is 50 ppm). Extraction of the metal involves roasting the ore to produce the oxide, followed by reduction and purification by electrolysis. The element is inert to non-oxidising acids but reacts with oxidising agents. In air, it will weather to produce the characteristic green patina of the carbonate. Copper will combine with oxygen on heating to produce CuO at red heat, and Cu2O at elevated temperatures.

    Pure copper has an electrical conductivity second only to that of silver and hence its main application is in the electrical industry. Copper is also the basis of many important alloys (e.g. brass, bronze and aluminium bronze) and has been traditionally considered to be one of the coinage metals, along with silver and gold, but being more common, is the least valued. It is one of the first metals ever to have been worked by man and is thought to have been mined for more than 5000 years.

    Notes

    Alpha brasses

    >65

    <35

    Alpha brasses are malleable, can be worked cold, and are used in pressing, forging, or similar applications. They contain only one phase, with face-centered cubic crystal structure.

    Alpha-beta brasses

    55–65

    35–45

    Also called duplex brasses. Suited for hot working. It contains both α and β' phase; the β'-phase is body-centered cubic and is harder and stronger than α. Alpha-beta brasses are usually worked hot.

    Beta brasses

    50–55

    45–50

    Can only be worked hot, and are harder, stronger, and suitable for casting.

    White brass

    <50

    >50

    Too brittle for general use. The term may also refer to certain types of nickel silver alloys as well as Cu-Zn-Sn alloys with high proportions (typically 40%+) of tin and/or zinc, as well as predominantly zinc casting alloys with copper additive.
