    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.

    Isolation

     

    Isolation: copper metal is readily available commercially so it is not normally necesary to make it in the laboratory. Most copper production is based upon sulphide ores containing little copper but quite a lot of iron. New cleaner technologies are now important but older processes present major environmental problems. Complex procedures are used initially to form a form of copper sulphide appropriate for final reduction via a copper(I) oxide. The resulting crude copper is purified using an electrolytic procedure involving plating onto pure copper cathodes.

    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.
