Aluminum Appearance & Characteristics
Members of the Council for Aluminium in Building are involved in all stages of construction, extrusion and design of systems, fabrication of products, finishing, production of associated products and final installation on site.
For blast furnace production to continue into the future even at current levels in the United States and other developed countries, continued progress must be made on reducing the coke rate of furnaces through coal injection. Significant progress has been made in evaluating the benefits of oxygen enrichment of the hot blast. Industrial trials are in progress to evaluate an oxy-coal injection system, which promises to allow for complete combustion at elevated coal injection rates. New, environmentally acceptable and economically feasible processes for new or replacement coke production capacity should be evaluated. If less coke is to be used in the blast furnace, the mechanical property requirements of the coke that is used will become more critical to maintaining permeability and stable furnace operation. If antiquated coke production methods cannot produce material of the required strength, exporting the environmental problems of coke production to developing countries with less stringent regulations may become functionally as well as socially unacceptable.

Amid the increasing concern for environmental preservation, there has been a rapid shift toward 4-stroke engines for motorcycles and outboard motors, as well as the adoption of emissions-reducing catalyzers and electronic fuel injection systems. There has also been an increasing movement toward hybrid vehicles, all of which has resulted in a revolution in vehicle engine and chassis design. Naturally, there is a concern that these additional systems will increase the weight of engines. Accordingly, the key is to use lightweight aluminum and lightweight design technologies to cancel out this added weight so that products can maintain past performance levels or even improve on them.
Aluminum is about 34% lighter than steel and is also excellent for casting thanks to its low melting point and good flow characteristics. Aluminum is also easier to reuse than other metals and there is almost no difference in the quality of the metal produced from recycled aluminum compared to new stock. Also, by combining it with other metals and selecting different kinds of thermo physical methods, it can be made to fit the needs of different uses. Taking advantage of these beneficial qualities, Yamaha uses aluminum in many of its products.
Particularly in products like motorcycles, snowmobiles and personal watercraft with which customers enjoy the handling and the feeling of man-machine unity that results, we at Yamaha consider reducing weight to be an important part of our manufacturing innovation process. And, one of the ways we reduce weight is by introducing aluminum parts. Presently, the ratio of aluminum (by weight) in our outboard motors is about 50%, while our large-class motorcycles are about 40%. And, as seen by the fact that we use about 3,000 tons of aluminum a month in our factories, improving the quality, the amount, and manufacturing process of aluminum parts has a vital effect on our products from their cost to their quality.
Against this backdrop, Yamaha CF Aluminum Die Casting Technology has developed with the result of our research, development and practice of aluminum die-casting in order to realize our manufacturing innovation.
