Characteristics:
Fine and powdery in texture, making them challenging to handle and collect
Frequently mixed with machining oils, other metal particles, or contaminants
Higher risk of contamination compared to larger scraps
Uses:
Titanium shavings are typically cleaned and melted down into ingots for reuse in manufacturing. While they are not suitable for applications requiring ultra-pure titanium, they are valuable for creating commercial-grade products, industrial coatings, or alloys used in construction and heavy machinery. Careful processing of these shavings ensures that even the smallest scraps of titanium contribute to the circular economy.
Recycling titanium shavings also helps reduce waste in industries where precision machining generates significant amounts of fine scrap material. By repurposing even the smallest particles, manufacturers can maximize efficiency while minimizing their environmental impact.
Titanium Bulk Weldable
Titanium bulk weldable materials are large, weldable scrap pieces that are commonly used in various industries. These materials are typically obtained from excess titanium stock, unused components, or surplus inventory. With their weldable nature, these titanium pieces offer versatility and convenience in fabrication processes, allowing manufacturers to efficiently create customized components and structures.
Characteristics:
Weldable composition suitable for joining with other titanium materials
