Process Essay: The Machinability Of Brass Metal

Improved Essays
Introduction

Brass is an alloy, a combination of copper and zinc. It contains around 67% copper and 33% zinc.
Commonly, Lead is also added to brass at a concentration of around 2%. Lead improves the machinability of brass.
Lead brasses have excellent machining qualities and can be blanked, sheared and milled.
Brass does not become brittle at low temperature like mild steel.
Brass also has excellent thermal conductivity. Its electrical conductivity ranges from 23 to 44% that of pure copper.
Copper is the main component, and brass is usually classified as a copper alloy
Brass is stronger and harder than copper but not as strong or hard as steel
Uses of brass metal

Brass metal is used to make water fittings, screws, radiators, musical instruments and cartridge casings for firearms. Brass is a fairly strong metal but relatively malleable, so it is easily mauled into a number of different

The addition of tin also improves the corrosion resistance. Iron makes the brass harder and makes the internal grain structure smaller to make proper shape of brass. Arsenic and Antimony are sometimes added to brasses that contain more than 20% zinc to inhibit corrosion. Other materials like manganese, silicon and phosphorus in a very small amount.
Manufacturing Process

Manufacturing process of brass involved combining the appropriate raw materials into a molten metal, which is allowed to solidify. After this process solidified metal are then changed through a series of operations to produce the desired brass stock. Actual manufacturing process depends on the desired shape and properties of the brass stock as well as on the machines and practices used in different brass plants. A very typical manufacture process used to produce brass sheet and strip.
Characteristics

The metal has both good heat and electrical conductivity and it is wear and spark

    It also used to eliminate the use of lead and cadmium and minimize the use of zinc and nickel. Also, it is used in immersion deposition for all surface replaceable ions to become tin. However, to attain good results, a good base metal preparation is needed. It is an environment-acceptable process and has a low cost. In electrodeposition, it is used as an alternative for tin-lead and cadmium coatings due to its good solderability and corrosion resistance.…

    Normally polyimides are compounded with graphite or glass fiber to get reinforcements to increase the flexural strengths. Thermoset polyimides exhibit low creep and high tensile strength, meaning this material has relative high endurance against high temperature and strains. This polymer coating has very good heat resistance and flame combustion. These properties enable polyimide to carry its job under harsh operating conditions. Generally the advantages of copper and its alloy include: • Good chemical resistance • Good thermal stability • Excellent mechanical properties • Excellent heat resistance Material…

    Titanium is a low-density element (has 60% density of steel), that be able to be highly modified by alloying and distortion processing. Titanium is non magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness, good toughness, low thickness, and excellent corrosion resistance, provided by various titanium alloys at very low to temperately elevated temperatures, allows weight savings in specific strength-efficient structures (e.g.…

    These include; high tensile strenght, ductility, corrosion resistant, low thermal expansion and is able to be soldered. So having these properties make it the clear option for use in electrical wiring. High Carbon Steel (Drill Bits): Steel is considered carbon steel when there is no specified minimum content of a certain metal such as; chromium, titanium, nickel etc. As the carbon percentage of steel rises, it will have the potential to become stronger and harder through the use of heat treating. But the downside to this is it will become less ductile.…

    It is also known for its low tensile strength and being very brittle (Xiong et al., 2011). Cast iron is suitable for making abrasion resistant surfaces such as “brake drums, clutch plates and sliding parts of machinery” (Xiong et al., 2011 p 2980). It can also be used in the manufacture of slideways in machine tools due to its property of being soft and tough. Steel steel is refined iron with an appropriate quantity of carbon added to it. This makes it extremely strong and tough.…

    Lightweight: With a specific weight of 2.7g/cm³, aluminium is used in many forms of transport including cars and aeroplanes and therefore reducing fuel consumption. Strength: By modifying the composition of the alloys, aluminium strength can be changed for whatever application it is required for. Corrosion-resistance: Aluminium generates a protective oxide coating naturally, and therefore makes it particularly useful for protection and conservation. Conductivity: Based on weight, aluminium is an even better conductor than copper, making it ideal to be used in overhead power lines. Ductility: aluminium has a low density and melting point, and these properties allow products to be formed up until the last stages of a product…

    However, the term may also refer to stiffness or resistance. Hardness characteristics of fabricated materials are presented in the table 1. From these results it shows that fabricated materials C filled by 2% charcoal shows the highest hardness number of 72 IRHD when compared with other filled fabricated materials. The reason behind that is due to continuous deposition of activated charcoal powder over the fabricated material. It has a great bonding capacity between fibre and matrix.…

    The damping ratio of ferrocement was also much higher than that of cast iron. Rahman et al. (1993).They assembled the lathe machine tool with a ferrocement bed and wanted to test its dynamic performance through a cutting test. The new lathe had a 50% deeper cut and the dynamic tests indicated that the new ferrocement lathe had greater natural frequency and damping ratio than a conventional lathe.
