1. Why choose this material

Aluminium:

-Density (near r.t.) 2.70 g·cm−3

-Melting point 933.47 K, 660.32 °C, 1220.58 °F

-Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust.

- Aluminium metal is too reactive chemically to occur natively

- low density and for its ability to resist corrosion

- Aluminium is a relatively soft, durable, lightweight, ductile and malleable metal with appearance ranging from silvery to dull gray

- The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.[6] Aluminium has about one-third the density and stiffness of steel. It is easily machined, cast, drawn and extruded.

--- Cast aluminium alloys yield cost effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al-Si, where the high levels of silicon (4.0% to 13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required

Brass

-Brass is an alloy of copper and zinc

-Because it is softer than most other metals in general use, brass is often used in situations where it is important that sparks not be struck, as in fittings and tools around explosive gases.[4]
