Aluminum Titanium Boron (AlTiB) delivers fine, equiaxed grains across many aluminum alloys. With controlled TiB2 particle distribution, the refiner promotes rapid nucleation and stable, low‑fade behavior. The result is lower porosity, improved properties, and more consistent casting, billet, and sheet output.
This Al‑Ti‑B master alloy introduces finely dispersed TiB2 that serves as potent nuclei during solidification. Titanium supports Al3Ti formation while boron stabilizes TiB2, achieving uniform grain size reduction. Benefits include higher strength, reduced hot cracking risk, better surface finish, and stable results from 1xxx to selected 7xxx alloys.
We hold over 100 patents, including two China Patent Award‑winning inventions, and helped draft the national standard for aluminum alloy additives. These products are engineered for process stability and repeatable results.
Certifications include IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. Quality control uses spectral analyzers, calibrated furnaces, and documented traceability. Four production bases and eight distribution centers support dependable delivery.
The refiner is used in primary melt treatment for ingot and continuous casting, extrusion billets, sheet and plate, wheels, and precision castings. Typical alloys include 6xxx billets, 2xxx/7xxx sheet, 1xxx electrical conductor, and foundry grades. Consistent refinement improves feeding, reduces segregation, and stabilizes properties through heat‑treat cycles.
Precisely engineered grades match alloy and process needs with controlled Ti and B. Standard and custom ratios are available with tight tolerances for chemistry, microstructure, and performance.
AlTi5B1 suits general‑purpose refinement. AlTi3B1 serves alloys sensitive to titanium pickup. AlTi5B0.5 is used where lower boron is preferred. All grades feature an aluminum matrix with optimized Ti:B ratios and clean TiB2 dispersion.
Titanium and boron contents are tightly controlled, with the balance aluminum and minimal impurities. In‑line spectral analysis and disciplined process control support repeatable effects and stable grain size.
Targets emphasize fine, uniformly distributed TiB2 particles. Performance is verified by grain size reduction tests, fade resistance evaluation, and melt response at industrial addition rates.
Supply forms include rods for precise in‑furnace addition and cored wire for automated feed. Ingots or waffles support bulk charging, with custom cut lengths available for controlled dosing. Dimensions and winding options promote consistent feed and low oxidation.
Moisture‑protected packaging and crate systems support safe storage and low contamination. Clear labeling enables traceability, and handling guidance helps preserve activity before use.
Addition rates are set by alloy, melt size, and target grain size. Guidance covers temperature windows, immersion practices, and contact time to activate TiB2 while avoiding excessive titanium pickup or dross.
The refiner is compatible with 1xxx, 3xxx, 5xxx, 6xxx, and selected 2xxx/7xxx alloys where controlled titanium is acceptable. Notes address silicon and magnesium levels and treatment timing for consistent results.
Degas and flux prior to addition to limit hydrogen and inclusions, improving nucleation efficiency. Refining and degassing fluxes help produce cleaner melts and more uniform grain refinement.
Production is certified to IATF 16949, ISO 9001, ISO 14001, and ISO 45001. Spectral analyzers, reduction and muffle furnaces, and in‑process checkpoints verify chemistry, microstructure, and performance.
Each batch carries full traceability with documented raw materials, process parameters, and QC results. Statistical process control and lot‑to‑lot comparison help ensure consistent TiB2 activity and predictable grain size.
Non‑standard Ti/B ratios, specialty forms, and custom lengths or winding can be provided. Technical experts support on‑site trials, melt audits, and ongoing optimization. Contact us to request a quote or schedule a trial.
Complementary master alloys include AlSr for modification, plus AlB, AlTi, AlZr, AlMn, and AlSi for refinement, modification, and strengthening. Alloying metal tablets (Mn, Fe, Cu, Ni, Cr, Ti) and refining/degassing fluxes support cleaner melts and downstream quality.
Four production bases, including a large Anhui plant with dedicated lines, provide stable capacity. Planned expansions at the Harbin headquarters will further enhance output. Eight distribution centers, including Fujian, Jiangsu, Chongqing, and Guangdong, enable rapid dispatch and standard stock programs to keep lines supplied.
