This mixture can be altered to produce new novel alloys, and bronze has dozens of useful blends for this reason. Besides a decorative metal, silicon bronze finds applications in marine hardware, electrical components, and chemical processing equipment, to name just a few of its uses. HRB . AutoDrill. Thomas Regional® are part of Thomasnet.com. Bronze is like any other alloy in that it is a mixture of certain metallic elements, which together have increased material properties over their pure forms. It is made using around 94-96% copper by weight, and the rest is typically 2.5-6% silicon and a mixture of other metals such as aluminum, zinc, lead, iron, manganese, and more. As with other copper alloys, silicon bronze is finding more and more uses by the day. Company. Thomasnet Is A Registered Trademark Of Thomas Publishing Copyright© 2020 Thomas Publishing Company. COVID-19 Response For reference, the Rockwell B hardness of copper is 51, showing that silicon bronze alloys are more resistant that its pure base metal. Malleable Iron-Brinell hardness of around 134. Indentation Diameter mm. Tungsten vs Tungsten Carbide - What's the Difference? Can Your Company Help Provide Critical Supplies? Silicon bronze comes in a range of tensile strengths, but it can easily surpass some other aluminum alloys and carbon steels if tempered correctly. Bridgeport Mill) Applications, Wide Multiple Spindle Head with Rod Guides. For the case of bronze, this standard material is UNS C36000 free cutting brass which has a machinability rating of 100%. Below, in Figure 1, is a qualitative chart depicting the composition of phosphor bronze: If looking for an aesthetically pleasing metal that can hold its own, consider a high alloy silicon bronze. We are using the power of our platform to aid in the mass shortage of critical supplies. ©2020 This machinability rating is compensated for by silicon bronze’s exceptional formability and weldability, which means machining may not be necessary, depending upon the application. California Do Not Track Notice. These values were averaged from a range of specific silicon bronze alloys in industry and are meant to provide an estimated range. Silicon bronze is more resistant to water corrosion than brass, making it highly useful for marine applications. For now, the main applications of this attractive metal are as follows: Consider silicon bronze if it seems applicable to your projects, and don’t hesitate to ask your supplier for more information. Thomas Register® and Besides these minor disadvantages, however, silicon bronzes stand above traditional alloys as an exceptionally resistant, yet handsome material for marine applications. It has low magnetic permeability and is conductive (though, it is typically not specified for its current-carrying capabilities). It is a mainstay in most blacksmith forges, as silicon bronze works especially well under high heat and can be cold formed between anneals. Aluminum- 58.6. A high modulus of elasticity suggests a stiff, often brittle material, while a lower value represents an elastic one. BRINELL HARDNESS: Drilled Diameter With Suggested Feed Rate Below: … Bronze: 3; Nickel: 4; Platinum: 4-4.5; Steel: 4-4.5; Iron: 4.5; Palladium: 4.75; Rhodium: 6; Titanium: 6; Hardened steel: 7-8; Tungsten: 7.5; Tungsten carbide: 8.5-9; Why It Is Important to Know the Hardness of Metals. The scale used in Table 1 is the Rockwell B hardness scale, which simply means many materials are rated by the standard Rockwell B hardness indenter machine and put into a comparative matrix. Hardness is a value that is dependent on the scale and describes a material’s resistance to surface deformation (scratching, etching, etc.). This chart shows you the approximate hardness conversion numbers for non-austenitic steels. So, while it doesn’t score highly in this category, it does not mean silicon bronze is difficult to shape. Even our competitors are asking to get involved in the AutoDrill magic!
