Morgan Bronze

CA 954 Aluminum Bronze is the most popular of aluminum bronze alloys, providing high tensile and yield, good ductility, weldability, and machinability, excellent resistance to wear, fatigue, and deformation under shock and overload. It's used as gears, worm wheels, bushings, bearings, wear strips, and pump parts in chemical, marine, aircraft, machine tool and earth moving machinery. Notice: The weights listed are the best estimates of the actual weights we will ship. They are a combination of the calculated theoretical weights and an average of actual weights. Our weights are conservative to the heavier side but there may be slight variations in weight from bar to bar. Stock allowances for these items are noted below.

C 172 Beryllium Copper is the most commonly specified beryllium copper and is available at Morgan Bronze in extruded and heat treated tubing. In its age hardened condition C 172 attains the highest strength and hardness of any commercial copper base alloy. The ultimate tensile strength can exceed 200 ksi and the hardness approaches Rockwell C45. This alloy is used as bearings for aircraft landing gear and pivoting members, bushings for tri-cone drilling bits, pressure housings for precision magnetometers and other instruments, as well as resistance welding applications.

C 95510 Heat Treated Nickel Aluminum Bronze is one of the highest strength nickel-bearing aluminum bronzes. It exhibits excellent yield, compressive strength, high hardness and adequate elongation. It is a good bearing material suitable for heavy duty and high impact applications. It exhibits excellent corrosion resistance, heat resistance, good machinability and weldability. Its additional strength is achieved through heat treating. It is used as heavy duty bushings and bearings, gears, and wear parts. It finds use in marine applications as well as pump parts, machine tool parts, aircraft parts and military applications. It is specified most often as bearing components in aircraft landing gear.

G2 Gray Iron is a pearlitic gray iron containing Type A graphite. Gray Iron bars made to this specification have optimal strength, wear and hardness when compared to the other gray iron grades. This material is well suited for applications requiring high resistance to wear and response to heat treatment. This specification is similar to ASTM A48A 48M, Class 40. The microstructure will contain Type VII, A, size 4-6 graphite as defined in ASTM A247. The matrix is fully pearlitic. The rim will consist of Type D, size 4-6 graphite in a pearlite matrix with small amounts of ferrite. Chill carbides will be less than 5% in any field at 100x and are well dispersed.

65-45-12 Ductile Iron contains nodular graphite in a matrix of ferrite with small amounts of pearlite. The ferritic structure gives excellent machinability with good surface finishes along with optimal impact strengths, fatigue properties, electrical conductivity and high magnetic permeability. This iron has approximately the same tensile and yield strengths as AISI 1020 Steel in the as-rolled condition. This specification conforms to ASTM A536 grade 65-45-12. The microstructure consists of Types I & II nodular graphite as defined in ASTM A247. The matrix is ferrite with approximately 5-25% pearlite. The “rim” will have a higher nodular count and will be mostly ferrite. Chill carbides will be less than 5% in any field at 100x and will be ...
