Alro Steel was established in 1948 by Al and Robert Glick and has grown to include Alro Plastics, Alro Industrial Supply and Alro Metals Outlet.

Bronze Tubing & Pipe

Bronze Tubing & Pipe

Bronze pipe and bronze tubing are made of alloys consisting primarily of copper, usually with tin as the main additive. It is hard and tough, and bronze was so significant in antiquity that the Bronze Age was named after it.

There are many different bronze alloys, but modern bronze is typically 88% copper and 12% tin. Commercial bronze (90% copper and 10% zinc) and architectural bronze (57% copper, 3% lead, 40% zinc) are more properly regarded as brass alloys because they contain zinc as the main alloying ingredient. They are commonly used in architectural applications.

The lead content in bearing bronze pipe and bronze tubing is between 7 percent and 15 percent. Highly leaded tin bronze alloys are free cutting, and they retain favorable thermal conductivity and good lubricity due to their lead content. Alloy 932 or C93200 is considered workhorse alloy and is widely used in many bearing applications.  Aluminum bronze pipes and tubes are made of the highest strength standard copper based alloy.

Alro offers 954 or C95400 and 959 or C95900 in standard sizes of rounds, tubes and rectangles. Aluminum in conjunction with iron and nickel in C95500 acts as a strengthener in these alloys. All of the aluminum bronzes can be heat treated, further increasing tensile strengths.

Typical end uses for bronze include: gears, valves, seats, fittings, fasteners, washers, pumps, bushings, machine parts, main spindle bearings, machine tool bearings, bearings for cranes, trunnion bearings, roll neck bearings, rolling mill bearings, linkage bushings for presses, fuel pump bushings, water pump bushings, diesel engine wrist pin bushings, forging press toggle lever bearings, hydraulic press stuffing box, hydraulic press main lining, pump impellers, and general purpose bushings.
