Low carbon steel compared to nylon

Extracts from this document...


To make a circuit board clamp 2 main modern materials are used, these are: * Low carbon steel * Nylon These two materials have many different properties and design issues and in this essay I am going to be looking at what they are and why that certain material has been used. First I'm going to look at the different properties of Low Carbon Steel. The properties I'm going to be looking at are the density, weight, machine ability, strength and cost. Low carbon steel has a carbon content of around 0.05-0.29%, this is less than the other types of carbon steel including medium, high and ultra-high carbon steel therefore it is more ductile. Firstly i'm going to look at it's density, this is a measure of how heavy an object is for a given size, for example the mass of material per unit volume. The density of this material is 0.28 lb/in3. Next is its strength, When strength is not a major concern, low-carbon steels are good choices because they are easy to handle (draw, bend, punch, swage, etc.), the tensile strength of low carbon steel is a maximum of 500 Mpa. ...read more.


The maximum density of nylon is 1.25 g/cc. Different forms of nylon are used widely all over the world, including for: * Apparel: Blouses, dresses, foundation garments, hosiery, lingerie, underwear, raincoats, ski apparel, windbreakers, swimwear, and cycle wear * Home Furnishings: Bedspreads, carpets, curtains, upholstery * Industrial and Other Uses: Tire cord, hoses, conveyer and seat belts, parachutes, racket strings, ropes and nets, sleeping bags, tarpaulins, tents, thread, monofilament fishing line, dental floss This material has been chosen to be used for the circuit board clamp as it will make the product more sellable as it will not damage the circuit board that it will be holding. I'm now going to look at 2 other materials that have not been used in our project and compare them and explain why they haven't been used. The two materials I'm going to look are Gold and Aluminium. First I'm going to look at aluminium. Aluminium is a soft, lightweight, malleable metal with appearance ranging from silvery to dull gray, depending on the surface roughness. Aluminium is nontoxic, nonmagnetic, and nonsparking. ...read more.


It has an extremely high melting point at 1060�C and has an atomic mass of 196.97, atomic mass is the mass of one atom of an element. Gold is heavy, it weighs over nineteen times more than water, and is almost twice as heavy as lead, Gold, like most metals, can be hammered into thin sheets (malleable) or drawn out into thin wires (ductile). Gold is not a widely used material but is used for lettering on honour rolls in schools, most jewellery and some ornaments. The reason this material has not been used for our project is because it would be far too expensive and probably too soft. I've looked at why these materials have not been used and now I'm going to conclude why the two materials that have been used (low carbon steel and nylon) was chosen for our cicuit board clamp. The main reasons for why we used low carbon steel are because: * It's strong * Cheapness * Easy to machine * Ductile and malleable The reasons for using Nylon are because: * Will not damage the circuit board * Tough * Strong * Abrasion resistant Mechanical Engineering Sector Nathan Sarahs ...read more.
