Custom Bronze Prototyping Services
Plethora offers innovative bronze prototyping services that combine software with precision machining tools. Our team of engineers and skilled machinists provides expert custom bronze prototyping services for industries that require precision bearings and bushings that run cooler and resist corrosion.
Advanced machining services for C936 High Lead Tin Bronze produce prototypes to precise tolerances that match your exact specifications. Our machining tools provide the rigidity, stability, speed, and cutting configurations essential for making high-quality bronze components. Without the special attention that we give to machining bronze, parts would fracture. We use lubricants and coolants required for optimal heat extraction.
Our machining services for bronze cover:
- Turning
- Grinding
- Milling
- Boring
- Cutting
- Finish Machining
CNC manufacturing done right, the first time.
We think critically about all aspects of your project to save you time and money. Plethora has the tools and materials you need, whether you’re looking for a prototype or a large production run.
Custom Bronze Prototyping Services Offer Better Conductivity Than Steel At a Lower Cost
Bronze alloys have superior hardness when compared to iron but less hardness than steel. Although bronze alloys have a lower melting point than steel, bronze provides better corrosion resistance. Bronze alloys also have a lower fatigue threshold than steel but offer better heat and electrical conductivity at a lower cost.
The combination of materials used to form bronze alloys offers high ductility, hardness, thermal and electrical conductivity, strength, and workability. The variety of alloys and mixtures used to form bronze results in varying hardness, plasticity, resistance to corrosion, and conductivity. Properties such as a high coefficient of friction and good thermal and electrical conductivity allow bronze to work well for bearings, bushings, threaded parts, electrical terminals, bolts, and nuts.
C936 Bronze Offers Corrosion Resistance and Excellent Machinability
Plethora works with C936 bronze—an alloy that contains 80% copper, 7% tin, and 12% lead. High Lead Tin bronze has good hardness, high corrosion resistance, a high coefficient of friction, and resistance to cracking. The higher lead content in C936 bronze allows for better lubricity, as required for bearing applications. The table below shows the critical properties of C936 bronze.
C936 Bronze Alloy Properties |
|
| Property | Rating |
| Nominal Brinell Hardness | 65 under 500 kg load |
| Nominal Tensile Strength (kilo-pound per square inch [KSI]) | 35 |
| Yield Strength (0.5% Extension under Load, min) | 20 |
| Nominal Density (lb/cu in @ 68oF) | 0.325 |
| Nominal Elongation (Percent in 2 inch) | 10 - 15 |
| Electrical Conductivity for Annealed Bronze (Percent IACS @ 68o F) IACS = International Annealed Copper Standard | 11 |
| Thermal Conductivity | 28.5 BTU/Sq Ft/Ft hr/oF at 68o |
| Machinability | 80 |
While C936 bronze joins by soldering and brazing, the alloy will not accept oxyacetylene welding or arc welding. Overall, C936 has better machinability than other bronze alloys.
Plethora Serves a Wide Range of Industries with C936 Bronze
Given the capability to withstand abrasion from dirt and debris, components made from C936 bronze protect mating surfaces from wear. Typical applications for C936 include pressure bearings, crankshaft main bearings, electric motor bearings, pump sleeves, rod bushings, rolling mill bearings, sleeve bushings, spacer bushings, and steel mill bushings.
Plethora’s bronze prototype components serve industries that include mining, hydraulics, electrical, refining, marine, and transportation. When you work with us, you can expect high-precision, performance, speed, accuracy, and reliability for any project. Our skilled machinists and proprietary software produce parts quickly and at the highest standard of quality.
