Titanium boron

When purchasing Titanium Boron, specifically Aluminum-Titanium-Boron (AlTiB) grain refiners, the chemical composition ratio is critical. The most common industry standard is 5% Titanium and 1% Boron (AlTi5B1). You must verify the microstructure quality, ensuring that TiAl3 particles are small (ideally <20μm) and TiB2 particles are well-dispersed to prevent agglomeration, which can cause defects in the final aluminum product.

Buyers should request a KBI (Kaufman) Test or a standard Grain Refinement Test report. This validates the material's ability to reduce the grain size of aluminum alloys effectively. Ensure the supplier provides a Certificate of Analysis (COA) for every batch, highlighting the impurity levels (such as Fe, Si, and V), as excessive impurities can negatively impact the electrical conductivity and mechanical properties of the end product.

Titanium Boron is primarily used in aluminum casting, extrusion, and rolling processes. It is available in various forms: Coiled Rods (9.5mm diameter) for continuous feeding into the melt, Waffle Ingots for batch melting, and Cut Rods for specific alloying needs. For high-end applications like aerospace or automotive engine components, the rod form is preferred for its precise addition rate and consistency.

A reliable supplier should be ISO 9001 certified for quality management. For international trade, ensure the product meets ASTM or EN standards relevant to master alloys. If the material is used in food-grade packaging (aluminum foil), verify that the supplier adheres to REACH and RoHS regulations to ensure the absence of hazardous substances.

Titanium Boron prices are heavily influenced by the LME (London Metal Exchange) aluminum prices and the cost of raw titanium/boron salts. To mitigate risk, consider long-term framework agreements with price formulas linked to the LME. To ensure quality, use third-party inspection services (like SGS or Intertek) to conduct pre-shipment sampling and testing at the supplier's warehouse.

Focus on technical transparency rather than just the lowest price. Ask for SEM (Scanning Electron Microscope) images of the alloy's microstructure. Suppliers on Made-in-China.com who are 'Diamond Members' or 'Audited Suppliers' often provide better after-sales technical support, such as guidance on the optimal addition rate (kg/tonne) for your specific furnace setup.

Titanium Boron is heavy and sensitive to oxidation if exposed to moisture for long periods. Ensure the supplier uses seaworthy packaging, typically wooden pallets with plastic shrink-wrap and steel strapping. For coiled rods, specify moisture-proof lining inside the crates. Clearly define Incoterms (e.g., CIF or FOB) and ensure the Harmonized System (HS) Code (typically 7605 or 7601) is correctly declared to avoid customs delays.

Always utilize secure payment methods and consider using the escrow or trade security services provided by Made-in-China.com. Avoid 100% upfront payments; a standard 30% deposit and 70% balance against the Bill of Lading (B/L) is common. For large-scale industrial orders, a Letter of Credit (L/C) provides the highest level of security for both the buyer and the seller.
