Question:
We have a project coming up which will require installation of 34 Keenserts (PN J1466P04).
The base material is Titanium 6-2-4-2 (AMS 4919).
Will a broaching tool sufficiently create the keyslots in this material. (How many needed, What is the cost)
Is a pneumatic tool worth purchasing for this application.
Answer:
Titanium 6Al-2Sn-4Zr-2Mo grade (also known as Ti 6-2-4-2) is a near alpha alloy known for its exceptional creep resistance, strength, and sturdiness, and is often used in a duplex annealed state. Due to its heat resistant nature and durability, 6-2-4-2 titanium materials are most commonly used in the engineering of aircraft and turbine engines (discs, blades, and impellers), airframe components, and high performance automotive valves. Ti 6-2-4-2 comes in a variety of standard specifications including AMS 4919, AMS 4975 and more.
Hardness: HRC 39 max, typical HRC 34-36.
Density: 0.164 lbs/cubic inch
Modulus of Elasticity: 16 msi
Coefficient of Expansion: 5.2 microinch/inch/degree F from RT to 600F
It means you have a max. hardness HRC 39, but typically 34-36

out of this blog, we know you require an installation tool for part number: J1466P04
the matching broaching tool is https://clinserts.com/BT332-2
so yes, your alloy is above 30HRC, so you require a broaching tool
we have one piece in stock left after that we need to make new ones
I would recommend to immediately buy 2 or 4 extra broaching blades (buy them per pair)
Here you see a video on how to use our tool
