These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility, or machinability.
22.
Their machinability is good and they have a balance of wear resistance and toughness ( i . e . between the D-and shock-resistant grades ).
23.
Machinability ratings can be used in conjunction with the Taylor tool life equation, VT ^ n = C, in order to determine cutting speeds or tool life.
24.
It should also be noted here that nanocomposite ceramic materials also offer interesting mechanical properties not achievable in other materials, such as superplastic flow and metal-like machinability.
25.
A method for improving machinability in spalted wood using methyl methacrylate was developed in 1982, and several white rot fungi responsible for zone line formation were identified in 1987.
26.
A letter " L " within the grade name indicates lead as an added ingredient; for example, 12L14 is a common grade that is 1214 with lead added for machinability.
27.
Of the non-metallic elements less often recognised as metalloids, selenium in the form of ferroselenium ( 50 58 % selenium ) is used to improve the machinability of stainless steels.
28.
Joe Talmadge claims it might be the ultimate high-end all-around stainless steel, due to high performance coupled with easier machinability and sharpenability than the other steels in this class.
29.
Early in the twentieth century, German silver was used by automobile manufacturers before the advent of steel sheet metal; for example, the famous bolsters, due to its machinability and corrosion resistance.
30.
Anodes are usually made from pure tungsten, or, when good machinability is required, lanthanum-alloyed tungsten, and are often machined to provide extra surface area to cope with power loading.
