A
typical example of this is the company’s manifold blocks, where high-speed
machining brass is chosen over aluminium because of its speed of machining,
typically 20% faster than aluminium, and the superior finish obtained.
Additionally brass swarf comes clean away in small fine chips rather than long
spirals, has a scrap value three times that of aluminium and, where drilled
cross holes meet brass, leaves no burr thus eliminating the need for subsequent
de-burring operations.
The
faster machining times of brass over aluminium, the lower raw material price
(brass is only two thirds the price of aluminium) and the premium price paid for
brass swarf more than compensates for the fact that aluminium is one third the
weight of brass.
In
addition brass does not need to be plated or painted to prevent corrosion and
when the product finally reaches the end of its long and useful life it can be
readily recycled without loss of properties. |
