A soft, white, non-ferrous alloy bearing material composed principally of copper, antimony, tin and lead.


A bearing metal of non-ferrous material, containing several tin-based alloys, mainly copper, antimony, tin and lead.


As defined by the International Telecommunica- tion Union (ITU), the altitude of the perigee above a specified reference surface serving to represent the surface of the earth. altitude tin


An ancient palm held tin whistle used for signalling orders aboard ship, consisting of a flat plate (keel) supporting a bent pipe (gun), terminating with a blow hole (orifice) at a hollow sounding sphere (buoy). Still used in the Navy to pipe dignitaries aboard a ship.


Weight of the goods alone without any immediate wrappings, e.g., the weight of the contents of a tin can without the weight of the can.


1. Along, straight tube, used in glass blowing, on which molten glass is gathered and worked. 2. A small, tapered, and frequently curved tube that leads a jet, usually of air, into a flame to concentrate and direct it; used in flame tests in analytical chemistry and in brazing and soldering of fine work. 3. See blowtorch.


A Copper-Tin alloy. Additions of up to 10% tin are soluble in copper and form soft ductile alloys which can be cold-worked. Further additions of tine result in the appearance of a hard constituent, such alloys being suitable for hot-working and for castings. The cold worked alloys are used mainly for coinage.

Admiralty Gunmetal (88: 10: 2, Cu: Sn: Zn)

Zinc is present as a deoxidizer and increases fluidity. This alloy is used mainly for castings requiring strength and corrosion resistance. An additional of 1% lead may be used to improve pressure tightness. The alloy may be used for bearings.

Cast 15% tin bronze is suitable for bearings.

Phosphorus increases strength and corrosion resistance.

Alloys containing up to 8% and 0.3% phosphorus can be cold worked and are used for instrument springs and steam turbine blades. Cast alloys contain up to 13 tin and up to 18% phosphorus are used mainly for bearings.

Alloys containing up to 9.4% aluminum are soft and ductile and are suitable for hot and cold working. Further additions result in the appearance of a hard constituent and are used for the hot worked condition and for castings. Aluminum bronzes have good mechanical properties, wear, fatigue and corrosion resistance. The 7% aluminum alloy often contains small additions of nickel, iron and manganese and is used for marine condenser tubes.

The 10% alloy with additions of nickel, iron and manganese is used for propellers.


Phosphorous Bronzes containing 10-13% Tin and 0.3-1% Phosphorous and Tim Bronzes containing 10-15% Tin are used for bearings where the loading is heavy.

Lead Bronzes are useful in that they have a high resistance to wear and have good thermal conductivity enabling the bearings to remain cool.

Sluntered bearings are made by heating a compressed powder mixture of 90% copper and 10% tin with an addition of graphite.

These bearings being semi-porous retain lubricant.


Soldering of a semiconductor chip to a substrate by vibrating the chip back and forth under pressure to create friction that breaks up oxide layers and helps alloy the mating terminals.


The application of a protective finish to a printed circuit board by dip soldering in a solder bath.
