New technologies put aluminium on the road
Article Abstract:
Development of the new 'Honda NSX' sports car has led to the development of lower cost mass-production of aluminium. The car's suspension parts were made of alloy A356 through ProGraM-controlled Gravity Die Casting. This new process involves making different die parts follow a water cooling curve, which is computer-controlled. This increases impact and tensile strength, as well as resistance to fatigue. It also means the casting has a refined grain, and has directional solidification. The use of aluminium parts was around five times as costly per unit strength, than using steel, according to Kunihiro Yasunaga, engineer. However, weight reduction costs would soon be paid off by low fuel consumption by the car. Modified press forming processes are also discussed.

Aluminium makes it onto the circuit
Article Abstract:
East-West Technology Partners Ltd. has developed a new process for the manufacture of printed circuit boards (PCBs). The process involves depositing alternate layers of aluminium and aluminium oxide to form insulating and conducting layers. The vapour deposition of aluminium is a relatively simple process which eradicates the need for the toxic chemicals used in conventional PCB manufacturing processes. The manufacturers say the technology is not suitable for all applications, but that it is ideal for lower-frequency, higher-temperature applications.

Bonded car sets new safety standard: novel bonded aluminium and composite structures have reduced weight and enhanced safety in a new car. The thinking behind them could change the way other products are made
Article Abstract:
Volume production of the Lotus Elise is based on adhesively bonded aluminium extrusions. The front structure is made from glass fibre composite sheets that are moulded into corrugated shapes. The aim was to produce a low cost replaceable structure which also protects drivers in both normal traffic and when racing, by absorbing off-axis impacts.
