ASTM F67 Titanium Bar | CP Grade 1-4 Surgical Implant Bar

ASTM F67 Commercially Pure Titanium Bar for Surgical Implant Applications

Beiyu supplies commercially pure titanium bar to ASTM F67 for surgical implant and medical-related applications. ASTM F67 covers unalloyed titanium for surgical implant material in Grade 1, Grade 2, Grade 3 and Grade 4, where the grade is selected according to the required strength and ductility. Commercially pure titanium is chosen for its biocompatibility and corrosion resistance in body-contact and medical-related components.

Implant-related bar should be quoted by grade, diameter, condition, tolerance and the controlling specification, because the material certificate and traceability requirements are usually strict for this application.

Grade and Standards

Size, Tolerance and Surface Condition

The tightened tolerance and any grain-size or hydrogen requirement are worth agreeing at enquiry rather than after the order, because both are set on the line and neither is corrected afterwards. Larger diameters outside the ground bar range are supplied peeled or turned, reviewed against the drawing before quotation.

Common Applications

Inspection and Documentation

Five inspections run at 100 percent on the precision finished bar route, meaning every bar rather than a sample from the lot. Chemistry and tensile testing are sampled instead, because both destroy the specimen.

The ultrasonic setting behind the words "ultrasonic tested"

Those six lines are worth writing onto a purchase order rather than accepting the words "ultrasonic tested", because a scan only becomes a meaningful pass or fail examination once the method, the coverage, the calibration reflector and the acceptance class are all fixed. The flat bottom hole is a calibration target, not a statement that every discontinuity of that size is detected.

Documentation

Material behind Beiyu mill products is produced on a triple vacuum arc remelt route, meaning the manufacturing mill remelts the ingot three times under vacuum. A third remelt is bought for cleanliness rather than for compliance: melt count is not what a chemistry table checks, so a double melted heat can satisfy the same composition limits. Ask which supporting records are available for the material being quoted; the document scope is agreed at enquiry.

Packaging and Export Information

ASTM F67 titanium bar is protected against surface damage and contamination during transport, and marked by grade and heat number where traceability is required. Packing is selected by diameter, length and shipment method.

RFQ Information Needed

FAQ

What is ASTM F67 titanium?

ASTM F67 is the specification for unalloyed (commercially pure) titanium used as surgical implant material, covering Grade 1 through Grade 4 by strength level.

Which CP grade is used for implants?

Grade 2 and Grade 4 are common; the grade is selected according to the required strength and ductility for the specific component.

What documents can be provided?

Mill test certificate, EN10204 3.1 documentation, heat number traceability and chemical/mechanical reports can be supplied when specified in the order.

Procurement Notes for ASTM F67 Titanium Bars

ASTM F67 titanium bar enquiries should define commercially pure grade, diameter, length, tolerance, annealed condition, surface finish and whether the material is intended for medical, dental, industrial or research use. Buyers should not rely on the phrase "CP titanium" alone, because Grade 1, Grade 2, Grade 3 and Grade 4 have different strength and ductility ranges.

For controlled purchasing, include certificate format, heat traceability, tensile requirement, straightness, cleaning requirement and whether EN10204 3.1 or customer-format documentation is needed. If the bar will be machined into medical-related components, include drawing revision, lot size, inspection points and packaging cleanliness requirements.

Also include bar end condition and any required inspection report format.
