Brass 464-H02

Also known as Naval Brass, 464 has excellent resistance to corrosion while maintaining average strength properties for copper alloys. This material is commonly used for marine fasteners, propeller shafts, heat exchangers, etc.

Overall Sizes
Largest Outside Diameter (OD_max)	2.91 in
Max Length (L), no bored features	9.5 in	Limited by machine clearance.
Max Length (L), with bored features	6.25 in	Features cut into the face of the part require more room for the tool to move into the part, subtracting from available room in the machine.
Minimum Wall Thickness	0.02 in
Max L:D ratio with no Tailstock	4	If the part is too long compared to its diameter, the cutting forces will push the part away, causing inaccurate dimensions. Allowing for a Tailstock can help exceed this limit.
Max L:D ratio with Tailstock	10	Even with a Tailstock supporting the end of the part, cutting forces near the middle of a long part can cause deflection and inaccurate dimensions.

Gears
Minimum Number of Teeth	12	Our gears are made by hobbing or single-tooth cutting, both of which have limitations under a tooth count of 12.
Maximum Helix Angle, Helical Gears	45°	Limited by machine clearance.
Available Tooth Sizes	0.5 mod hob	20° pressure angle
	0.6 mod hob	20° pressure angle
	0.7 mod hob	20° pressure angle
	0.8 mod hob	20° pressure angle
	1 mod hob	20° pressure angle
	1.25 mod hob	20° pressure angle
	1.5 mod hob	20° pressure angle
	12 DP hob	14.5° pressure angle
	16 DP hob	14.5° pressure angle
	20 DP hob	14.5° pressure angle
	1 mod hob	14.5° pressure angle
Maximum Gouge	3 times module	The maximum allowable distance for the gear cutting tool to enter the part. Features nearby to the gear surface will get gouged if they are too close.
Maximum Number of Gears per Part	4	Be aware of gouging when combining gears in one part. See: How to Make Stacked Compound Gears and Herringbone Gears
