Executive Summary 1. We see the company considering the penetration to the new market with a new product. After testing‚ their prototype cushion pads‚ consisting of curled metal‚ performed superiorly to asbestos pads‚ which are currently the industry standard compliment product to pile drivers. 2. Despite the fact that there’s no such a product on the market at the moment. The copmany is likely to face competition from the asbestos pads market (a substitute product) 3. The potential market

ability to identify metals is an extremely important one. With this ability‚ we can correctly assign different traits‚ and use the metal in its most suitable environment. This is important to many industries‚ where metals play an increasingly large role. Determining the identity of the metal is paramount to determining what conditions to use the metal under. This seemly simple task is‚ however‚ can be quite complex‚ as there are many ways by which one can identify a metal‚ each with varying amounts

Abundance and Extraction of Metals 1. a Mineral - A mineral is a naturally occurring inorganic solid‚ with a definite chemical composition‚ and an ordered atomic arrangement. b Ore - Deposit in the Earth of valuable metals contained in minerals. c Economic Natural Resource Deposit - This is a natural deposit of something that is economically viable to mine‚ refine and sell. Hence the deposit must be big enough to last for a large period of time‚ so that it will make enough money for the

Four heavy metals that are toxic to humans are: 1. Cadmium (Cd) 2. Lead (Pb) 3. Mercury (Hg) 4. Arsenic (As) (B) EXPLAIN IN GENERAL TERMS WHY THESE HEAVY METALS ARE TOXIC TO LIFE. These heavy metals are toxic to life because they generally bind tightly and permanently to the active sites of enzymes‚ thus destroying their catalytic

The Metal Injection Moulding process (MIM)‚ considered as a development of the Powder Injection Moulding (PIM)‚ became‚ over the years‚ a competitive manufacturing process for small components‚ offering an alternative to other processes‚ more expensive to create these parts. History of the technology The PIM process was at first developed in the 1930s in the USA. This process was originally intended for ceramics. Then‚ during the Second World War‚ metal powders appeared. The process of Metal

The transition metals are placed in the centre of the periodic table‚ between groups 2 and 3. They are generally hard and dense‚ and less reactive than the alkali metals. Iron‚ copper‚ silver and gold are important transition metals. The transition metals: overview The elements in the centre of the periodic table‚ between groups 2 and 3‚ are called the transition metals. Most of the commonly used metals are there‚ including iron‚ copper‚ silver and gold The transition metals Common properties

The alkali metals are found in group 1 of the Periodic table. They are very reactive metals and do not occur freely in nature. Alkali metals are malleable‚ ductile‚ and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium‚ sodium‚ potassium‚ rubidium‚ cesium‚ and francium. Lithium The mineral petalite‚ which contains lithium‚ was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the
