This question is about alloys.
Which metal is the main constituent of brass? Select one option:
Which two metals are commonly alloyed with iron to produce stainless steel? Select two options:
Give two properties of stainless steel that make it suitable for cutlery. Choose from the list:
Table 1 shows information about some alloys of titanium.
Table 1
| Titanium alloy | Other elements in alloy | Strength | Used in |
|---|---|---|---|
| T1 | 6.0% aluminium, 4.0% vanadium | very high | jet engines, spacecraft |
| T2 | 0.2% palladium | high | chemical process pipes |
| T3 | 1.5% nickel, 0.8% molybdenum, 0.5% cadmium | high | heavy machinery |
Calculate the mass of titanium in 12.5 kg12.5 \text{ kg}12.5 kg of titanium alloy T1. Use Table 1.
Suggest why alloy T1 is used in spacecraft structures. Use Table 1.
Alloys used in food processing machinery must not contain toxic elements. Suggest why alloy T3 is not used in food processing machinery. Use Table 1.
