Bronze is an alloy of copper and tin. However, the name is now applied to other alloys that do not contain tin.Material properties:
|Density kg/m3||8200 to 8800|
|Modulus of elasticity E GPa||96 to 120|
|Modulus of elasticity G GPa||36 to 44|
|Poisson's ratio v||0.34|
Bronze and brass are very similar when machining. TCT tools work very well with a very shallow back and side rake (see Lathe Tools).
We reviewed the Glanze TCT tools.
These tools have a steel body with separate TCT bits that are pre-machined to the correct angles. When the bit wears out or gets chipped then you just replace it.
Note that when machining rough castings it is very easy to chip the tools, so take that into account and use small cuts at first.
