Aluminium alloy

HARDNESS Hardness of a material is most commonly defined as the measure of its resistance to penentration by an indenter.Hardness is also measure of strength and often has the units of stress .The indenter is often fabricated from a hard material such as diamond or hardened steel.The tips of the indenters may be conical,pyramidal,or spherical in shape.The indenter tips may also be relatively small(nano-or micro-indenters) or very large(macroindenters).Since indentation tests are relatively easy…

Reaction # Observations Equation 1 We mixed Aluminum Sulfate with Barium Nitrate in two test tubes. The Barium Nitrate is a clear liquid that had no smell. The Aluminum Sulfate also was a clear liquid with no scent. When mixed, the center of the liquid turned into a milky white precipitate. After 2 minutes the white substance sank to the bottom while the clear liquid sat on top. Al2(SO4)3(aq)+3Ba(NO3)2(aq)--> 2Al(NO3)3(aq)+3BaSO4 (s) 2 First we felt the material of a piece of Magnesium.…

Ceramics material are compounds between metallic and non-metallic elements where it most frequently oxides, nitrides, and carbides(William D.callister,JR, David G. Rethwisch,2015). This material use for technical applications are commonly based on aluminium oxide. The properties of ceramics which are insulative to the passage of heat and electricity and more resistant to high temperature and harsh environment(William D.callister,JR, David G. Rethwisch,2015). Ceramics in cochlear implants use for…

The Autobiography of a Jacket I started off as a small section of cotton on the Farms of North and South Carolina. I went through the process that every piece of cotton wishes to go through. After going through the gen and being packaged, I was sold to a large company. I went through the hardship of being turned into yarn. The only thing that eased the pain was my friend, Fleece. I was slowly shaved away, 5 millimeters of cotton at a time, and was sent away to the cleaning and blending…

First Mineral: My first mineral of choice is Titanium. Titanium is a metal that was discovered in 1791 by William Gregor. A few common properties are its low density, inflexibility, resistant to extreme temperature, and corrosion. Ti is titanium chemical formula. Titanium is vital in my everyday uses for instance my newly purchased wallet, Apple laptop that I use for school and the golf cart I drive around the park. Dentist use titanium for patients who receive teeth implants. Titanium powder…

Before starting the Thickness of Aluminum Foil Lab, there were some questions that needed to be answered in order to have full a understanding of the topic. One very important thing in the experiment is measurements, and knowing the difference between a direct and indirect measurement was crucial. A direct measurement is when you measuring the exact object with instruments. A indirect measurement is when you are finding the measurement of something other then the actual object (n.d, 2015).…

Obtain a tin paint can, and cut the bottom off with a can opener. Cut a piece of wire mesh 7.5 inches in length, and 12 inches in width. Tie the ends of the wire mesh together with a piece of wire to form a cage. Place approximately 2 inches of Roxul Insulation on the inside of the can, and set the wire cage inside the can to secure the position of the insulation. Next, bind the tin can, wire mesh, and insulation together, with foil tape, by taping from the inside to the outside two or three…

The testable question asked what is the actual percent yield of copper produced in grams/milliliters from the reaction of 2 g of solid copper (II) sulfate pentahydrate and approximately .25 g of aluminum foil in 10 mL of water versus the theoretical yield of copper metal. The hypothesis stated that if a reaction occurs between 2 g of solid copper (II) sulfate pentahydrate and 2 mL of 6 molar hydrochloric acid with approximately .25 g of aluminum foil, then the actual percentage yield of copper…

History: Alcoa was founded by Charles Martin Hall in 1888. Originally the company’s name was Pittsburgh Aluminum Company but in 1907 was renamed Aluminum Company of America. Alcoa is best known for its work with lightweight metals and today “Alcoa is a global leader in lightweight metals technology, engineering and manufacturing” (Alcoa Corporate Overview). In 1890 the company was trying to find a market for aluminum products. The first big product manufactured with Alcoa’s aluminum was…
