ASTM F136 Titanium Internally Threaded Piercing Barbell

Description Of ASTM F136 Titanium Internally Threaded Piercing Barbell

ASTM F136 Titanium Internally Threaded Piercing Barbell is a precision-made body piercing jewelry component manufactured from implant-grade Ti-6Al-4V ELI (Extra Low Interstitial) titanium alloy, also known as Grade 23 or UNS R56401. This material is specified by ASTM F136, the standard specification for wrought titanium-6aluminum-4vanadium ELI alloy for surgical implant applications. It is widely used in medical implants and body piercing jewelry due to its outstanding biocompatibility, corrosion resistance, and mechanical strength.

The barbell consists of a straight shaft with internal threads at both ends and two externally threaded balls. The internal thread design means the shaft exterior is completely smooth, reducing friction and trauma when inserting through the piercing channel. The shaft is precision CNC-machined from ASTM F136 titanium bar, and the balls are machined and polished to a mirror-like finish (Ra ≤0.2μm). The threads are carefully cut to ensure smooth and secure assembly. The barbell is available in gauges of 1.2mm and 1.6mm, bar lengths from 6mm to 50mm, and ball diameters from 3mm to 8mm. Anodized colors are available without dyes or coatings.

Because the material is nickel-free and biocompatible, ASTM F136 titanium internally threaded piercing barbells are suitable for sensitive skin, new piercings, and long-term wear. They resist corrosion from body fluids and can be autoclaved for repeated sterilization. Custom sizes, colors, and packaging are available upon request.

Features Of ASTM F136 Titanium Internally Threaded Piercing Barbell

• Implant-Grade Material: ASTM F136 Ti-6Al-4V ELI (Grade 23), the same material used in surgical implants.

• Internally Threaded Design: Smooth shaft exterior minimizes trauma to the piercing channel during insertion and removal.

• High Strength-to-Weight Ratio: Density 4.43 g/cm³, tensile strength ≥860 MPa, yield strength ≥795 MPa.

• Mirror-Polished Surface: Ra ≤0.2μm for smooth insertion and comfortable wear.

• Precision Threading: Smooth and secure assembly between shaft and balls.

• Anodized Colors: Blue, purple, gold, rainbow, black, and custom colors without dyes.

• Autoclavable: Withstands repeated sterilization at 121°C–134°C.

• Multiple Sizes: Bar lengths 6–50mm; gauges 1.2mm, 1.6mm; ball sizes 3–8mm.

• OEM & ODM: Custom sizes, colors, logos, and packaging available.

Usage Precautions and Limitations Of ASTM F136 Titanium Internally Threaded Piercing Barbell

• Professional Piercing Recommended: For new piercings, have the jewelry installed by a professional piercer using sterile techniques.

• Sterilization: Autoclave at 121°C–134°C before use for new or healing piercings. Do not use harsh chemicals or abrasive cleaners.

• Cleaning: Clean with mild soap and water or a saline solution. Avoid chlorine, bleach, and abrasive cleaners.

• Thread Care: Do not over-tighten the balls, as this can damage the threads. Check tightness regularly to prevent loss.

• Compatibility: Verify that the barbell gauge and thread size match your piercing and desired ball size. Mismatched threads can cause damage or insecure fit.

• Allergy Information: ASTM F136 titanium is nickel-free and biocompatible. However, individuals with known allergies to aluminum or vanadium should consult a physician before use.

• Inspection: Inspect the barbell regularly for scratches, cracks, or damaged threads. Replace damaged components promptly.

• Not a Toy: Keep away from children. Do not swallow or inhale. Not intended for use as a toy or food-contact item.

• Quality Assurance: Ensure that the supplier provides material certification including chemical composition, mechanical properties, and compliance with ASTM F136.
