Titanium rivets

Buyers should primarily distinguish between Grade 2 (Commercially Pure) and Grade 5 (Ti-6Al-4V). Grade 2 offers excellent corrosion resistance and formability, making it ideal for chemical processing. Grade 5 is an alpha-beta alloy providing high tensile strength and is the standard for aerospace and automotive applications where the strength-to-weight ratio is critical.

For aerospace applications, ensure compliance with AMS (Aerospace Material Specifications) or NAS (National Aerospace Standards). For general industrial use, rivets should adhere to ASTM B348 (bars and billets) or ASTM F67/F136 (medical grade). Always request a Material Test Report (MTR) and EN 10204 3.1 certification to verify chemical composition and mechanical properties.

Selection depends on the application: Countersunk heads are essential for aerodynamic or flush surfaces, while Button or Pan heads provide greater bearing surface. You must also specify if you require Solid Rivets, which offer the highest joint integrity but require heavy equipment, or Blind Rivets (Pop Rivets), which are preferred for single-sided access and faster assembly in light-duty structures.

Titanium is prone to galling (cold welding). To mitigate this, specify treatments such as Anodizing (Type II or Type III), which increases surface hardness, or Molybdenum Disulfide (MoS2) coatings for lubrication. For aesthetic or identification purposes, Color Anodizing can be used without compromising the metal's integrity.

Avoid 'too-good-to-be-true' pricing, as scrap-melted titanium may contain impurities. Conduct Third-Party Inspections (TPI) via agencies like SGS or TÜV at the factory. Request a PMI (Positive Material Identification) test using XRF analyzers before shipment to ensure the alloy grade matches your PO.

Titanium raw material cycles can be long. Negotiate a staggered delivery schedule for large orders. For custom dimensions, suppliers on Made-in-China.com typically require an MOQ of 5,000–10,000 pieces; however, you can negotiate lower MOQs by paying a set-up fee or sourcing from suppliers with 'Ready-to-Ship' stock of standard sizes.

Due to the high value-to-weight ratio, use vacuum-sealed plastic packaging to prevent surface abrasion during transit. For international shipping, ensure the HTS code 8108.90 (Titanium articles) is used correctly to avoid customs delays. For urgent aerospace needs, Air Freight is recommended to minimize capital tie-up in transit.

Utilize Secured Payment services provided by Made-in-China.com to ensure funds are only released upon confirmation of receipt and quality. Always define Quality Acceptance Criteria (AQL) in the contract, specifying that final payment is contingent upon the goods passing a pre-shipment inspection.
