There are two Camshaft Material Types
1. CHILLED CAST IRON CAMSHAFTS
“So if it ain’t Chilled cast, it ain’t good enough. “
For mass production of Camshaft Blanks and is the best material for producing Performance Camshafts. It’s that good reliability wise that we manufacture most of our Standard Camshafts in this way too.
What is Chilled Cast ?
When the camshaft is cast in the foundry, the iron is poured and hardened off very quickly. ( known as chilling ) This causes the material to form a matrix of carbide on the camshaft lobe. This material will cut glass and is exceedingly scuff-resistant.
2. MACHINED BILLET CAMSHAFTS
Used for low quantity Camshaft production. Generally costs more due to the additional work involved in producing this type of Camshaft.
What is a Machined Billet Camshaft ?
The camshaft is turned from a round steel bar. It is then Nitride-Hardened after grinding to ensure hardness and reliability of the Camshaft Lobes.
