Though the use of carbon is most common for the production of this metal alloy, other alloying materials like tungsten, chromium and manganese are also used. The proportions and forms in which these elements are used, affect the properties of the steel that is produced – increasing the carbon content for instance, increases its strength.
Additive Manufacturing (AM) is an appropriate name to describe the technologies that build 3D objects by adding layer-upon-layer of material, whether the material is plastic, metal, concrete or one day…..human tissue.. Common to AM technologies is the use of a computer, 3D modeling software (Computer Aided Design or CAD), machine equipment and layering material.

Further, the plastic shrinks as it cools, and this tendency must be compensated for by using oversized mold cavities. Molds are expensive, from several thousands to millions of dollars each. Plastic materials are rheologically complex, and as a result many factors can affect the properties and dimensional accuracy of parts made from them.
Alloy Properties Uses; Brass (alloy of copper and zinc) Non-ferrous metal that is strong and ductile, casts well and is gold coloured but darkens when oxidised with age, a good conductor of heat
Plastic became a special target because, while so many plastic products are disposable, plastic lasts forever in the environment. It was the plastics industry that offered recycling as a solution. In the 1980s the plastics industry led an influential drive encouraging municipalities to collect and process recyclable materials as part of their ...
Plastic and Metal Material Properties When designing plastic or metal parts, your material's mechanical, physical, thermal, and electrical properties are often critical When you design a part, much of its functionality will depend on obvious factors like its shape, size, wall thicknesses, locations of connection points, and so on.
Plastics are ideally suited to the ergodynamic curves which make modern tools easy and safe to use. Durable: Plastics are hygienic, hardwearing and easily cleaned and maintained. They do not corrode, like metals, or rot like other organic materials. They are oil- and acid-resistant, an important property for tools and can be made shatter-resistant.

• Plastic deformations of single crystal metals - In the single crystal metal - slip mechanism: dislocations move through the metal crystals like wave fronts, allowing metallic atoms to slide over each other under low shear stress -Slip process begins within the crystal when the shear stress on the slip plane in slip
Properties, uses, and occurrence. Together with gold and the platinum-group metals, silver is one of the so-called precious metals. Because of its comparative scarcity, brilliant white colour, malleability, ductility, and resistance to atmospheric oxidation, silver has long been used in the manufacture of coins, ornaments, and jewelry.
The need for higher temperature and higher performance materials has led to the use of aromatic polysulfones, aromatic polyimides, aromatic polyketones, and aromatic polysulfides in demanding components and applications like medical trays, surgical and dental instruments, medical electronic components, drug delivery components, and machined parts.
The first commercial metal plating plastic process was developed in the early 1960s, primarily for use in the automotive industry. Automobile manufacturers were seeking ways to make their vehicles more fuel efficient, which led to the increased use of lightweight plastic …
Apr 26, 2017· What property of metals led to the use of plastic or wood handles on many metal cooking utencils? What are the advantages of wooden cooking utensils over metal or plastic ones? Why cooking utensils have handles made of wood or plastic?
Jun 01, 2001· Uses include custom-molded heat sinks on circuit boards, as well as tubing for heat exchangers in appliances, lighting, telecommunication devices, business machines, and industrial equipment used in corrosive environments. Heat sinks often involve plastic overmolded on a metal …
Plastic problems. Unfortunately, some of plastic's best properties – its durability and long-lasting life – are the things that cause problems in the environment. Many plastics, such as water bottles and packaging, are designed to be used just once.
Plastic materials for personal protection equipment for schools, retail, dining, medical, and office use. Plastic Properties Table Sort, compare, and find the plastic material suited for your application.
Mar 19, 2018· Metal vs Plastic. Compared to metal, plastic has a low melting point, is highly malleable, and can be molded easily into basic or complex forms. That malleability also increases the fabrication and production of parts and pieces. Unlike metals, finishes and colors can be added before fabrication and the need for certain post-treatment processes ...
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being light weight, durable flexible, and inexpensive to produce, has led to its widespread use.
The plastic can be any of a number of varieties, and its exact optical properties will determine what the output of the LED looks like. Some plastics are diffusive, …
