SPECIFICATION CROSS-REFERENCE CHART

Concast offers a complete line of stocked and custom-made cast alloy products. Standard alloys include manganese bronze C86300, lead-free C89835, tin bronze C90300, leaded tin bronze C93200 (SAE 660 bearing bronze), aluminum bronze C95400, nickel aluminum bronze C95500, and aluminum bronze C95900. These continuous cast bronze alloys are available in rods, tubes, rectangles and square shapes and manufactured to ASTM B standards and specifications. When our customers have needs for special alloys and sizes, we design the right products to meet their specific needs.

We offer special alloys, shapes, and sizes in the ASTM-B 505, 800 and 900 series specifications. Almost any extruded shape profile can be produced using continuous-cast technology. Concast can also supply centrifugals up to 30". Continuous cast bronze custom tubes, squares and unique shapes can be produced to within .005" tolerance in sizes ranging from 1/2" to 16", cut to custom lengths.

We produce alloys in Leaded Red Brass, Leaded Tin Bronze, Aluminum Bronze, and Manganese Bronze. To view the alloys we provide by family, just click one of the blue titles below.

LEADED TIN BRONZE

The lead content in high leaded tin bronze alloys is between 7 percent and 15 percent. These alloys are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. Alloy C93200 , also termed bearing bronze, SAE 660, SAE 660 bronze, and SAE 660 bearing bronze, is considered this family’s workhorse alloy and is widely used in many bearing applications.

C93200

LEAD-FREE

Alloy C89835 is a C932 lead-free replacement alloy. Concast is offering this product as a standard-stocked alloy over 90 items in inventory and sizes up to 4.0" OD. This standard-stocked alloy supports the market demand for lead-free material and compliance with the 3874 Reduction of Lead in Drinking Water Act (effective January 2014).

C89835

LEADED RED BRASS

This group of alloys is typically found in plumbing applications. The most widely used alloy in this family is C84400. Leaded red brass is known for reasonable cost with good machining and casting properties. The lead content ensures pressure tightness. Red brass is also used for low-cost bearing materials under low loads.

C84400

MANGANESE BRONZE

Manganese bronzes can operate under very high loads and speeds. However, bearing applications require reliable lubrication. Besides excellent mechanical qualities, these alloys have good corrosion resistance. The standard alloy in this group is high tensile C86300, which is comprised of copper, manganese, aluminum and iron. This combination raises the tensile strength to over 110,000 KSI.

C86300

ALUMINUM BRONZE

Aluminum bronze is the highest strength standard copper based alloy. Concast produces C95400, C95500 and 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.

TIN BRONZE

Tin bronze alloys are typically found in gear, high-strength bushing and bearing applications where high strength and low speeds and heavy loads are present. Other high-strength applications for these alloys are pump impellers, piston rings, steam fittings, valve bodies. High tin bronze castings are utilized in movable bridge components, turntables for bridges and other structures for fixed and expansion bearings with slow or intermittent movement with heavy loads.

HIGH-LEADED TIN BRONZE

Tin bronze alloys are typically found in gear, high-strength bushing and bearing applications where high strength and low speeds and heavy loads are present. Other high-strength applications for these alloys are pump impellers, piston rings, steam fittings, valve bodies. High tin bronze castings are utilized in movable bridge components, turntables for bridges and other structures for fixed and expansion bearings with slow or intermittent movement with heavy loads.
