Bronze is used to make bronze wool for woodworking applications where steel wool would discolor oak. Phosphor bronze is used for ships' propellers, musical instruments, and electrical contacts. [23] Bearings are often made of bronze for its friction properties. It can be impregnated with oil to make the proprietary Oilite and similar material ...
Protective elements for bronze fountains are particularly important, since water is one of the leading causes for alterations or corrosion in a bronze. [2] Bronze sculptures incorporated in fountains will need more layers of wax, because the spray of water will cause deterioration of the wax at a faster pace than would normally happen.
Brushed stainless steel or dull polished metal [1] is metal with a unidirectional satin finish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad. Commonly brushed metals include stainless steel, aluminium and nickel.
#7 Finish. A #7 finish is produced by polishing with a 280–320 grit belt or wheel and sisal buffing with a cut and color compound. This is a semi-bright finish that will still have some polishing lines but they will be very dull. Carbon steel and iron are commonly polished to a #7 finish before chrome plating.
Mill finish is the surface texture (or finish) of metal after it exits a rolling mill, extrusion die, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil.
Tumble finishing, also known as tumbling or rumbling, [1] is a technique for smoothing and polishing a rough surface on relatively small parts. In the field of metalworking , a similar process called barreling , or barrel finishing , [ 2 ] works upon the same principles.
They are bronze casts with some silver-colored parts, which originate from the Anatolian region. [2] Similar processes can be found on some ancient Egyptian copper sheets. [ 3 ] Another example of early chemical coloring of metals is the Nebra sky disk , which has a green patina and gold inlays.
Mass finishing is a group of manufacturing processes that allow large quantities of parts to be simultaneously finished. The goal of this type of finishing is to burnish , deburr , clean, radius, de-flash , descale , remove rust , polish, brighten, surface harden , prepare parts for further finishing, or break off die cast runners.
