Introduction Brasses are copper zinc alloys. It is a substitutional alloy. Brass has higher malleability than copper or zinc. In general‚ they have good strength and corrosion resistance‚ although their structure and properties are a function of zinc content. The relatively low melting point of brass (900 to 940°C‚ depending on composition) and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc‚ the properties of the brass can

Premium Tensile strength Steel Aluminium
Abstract Precipitation hardening‚ or age hardening‚ provides one of the most widely used mechanisms for the strengthening of metal alloys. It influences some properties of the alloys such as strength‚ hardness and ductility. The purpose of this experiment was to test the effect of temperature and aging time on strength and hardness of 6060 aluminium alloy samples that have roughly similar compositions by subjecting them to different temperatures for different periods of time. The experiment showed

The graduations are oversized by a proportionate amount‚ for example‚ when constructing a pattern for aluminium alloys‚ the pattern maker uses a contraction

ECONOMICS COMMENTARY – 1 Recently‚ demand for Aluminium has increased (data mentioned in article). Demand is the various quantities of a good a consumer is willing and able to buy at different price levels during a particular time period. The supply of Aluminium is steadily increasing‚ but the demand is likely to overtake supply‚ which is the various quantities of a good a producer is willing and able to produce at different price levels during a particular time period.

Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise
