The short answer is yes, absolutely. Metal briquetting presses are specifically designed to compact a wide variety of metal chips, turnings, and shavings into dense, dry briquettes.

However, the effectiveness, economics, and specific process requirements can vary significantly depending on the metal type.

Here's a detailed breakdown:

Metals Commonly and Successfully Briquetted:

Steel & Cast Iron (Ferrous):The most common and ideal application. Ferrous chips compress extremely well into very dense, high-value briquettes.

Benefits: Dramatically reduces oxidation (rusting), lowers freight costs, and fetches premium prices from mills and foundries as a clean furnace feed.

Aluminum:Also an excellent candidate. Aluminum chips are often long and stringy, taking up vast space and easily contaminated with coolant.

Benefits: Briquetting removes up to 95% of the residual coolant/oil, increases bulk density by up to 10x, and produces a briquette that is highly valued by secondary aluminum smelters. The process also reduces the risk of spontaneous combustion (associated with wet, fine aluminum fines).

Copper, Brass, Bronze (Copper Alloys):Highly valuable chips that are perfect for briquetting.

Benefits: Prevents loss of valuable material as fine dust, creates a clean, premium product for non-ferrous metal recyclers, and improves melting efficiency due to lower surface area and less oxidation.

Stainless Steel:Excellent for briquetting. The high value of the material makes the ROI on a briquetter very attractive.

Benefits: Preserves the alloy integrity by minimizing oxidation during storage, reduces volume for cost-effective transport, and delivers a high-purity feedstock.

Metals with Specific Considerations:

Titanium:Technically possible, but requires extreme caution. Titanium and especially titanium fines are pyrophoric—they can ignite spontaneously, especially when dry, hot, or under pressure.

Process Requirement: Briquetting must often be done under an inert atmosphere (like nitrogen) to prevent fire/explosion risks. Not all standard briquetting presses are equipped for this.

Magnesium:Similar to titanium, magnesium chips and fines are highly flammable and explosive.

Process Requirement: Extreme caution is required. Briquetting is sometimes done with specialized safety protocols and possibly inert atmospheres. It is less common than for safer metals.

High-Temperature Alloys (Inconel, Monel, Hastelloy):

These can be briquetted successfully. Their high value justifies the process.

Consideration: They are often very tough and work-hardened, which may require higher pressure from the press for effective compaction.

Key Factors That Determine Success:

Chip Size and Geometry: Long, stringy "birds nest" chips may require pre-processing (like crushing/shredding) for optimal feed into the press and a homogeneous briquette.

Moisture and Oil/Coolant Content: While briquetting presses expel liquids, an extremely high fluid content (e.g., >25%) might require pre-draining. The extracted oil/coolant can often be recovered and reused.

Press Pressure: Different metals require different optimal pressures. A good industrial press will have adjustable pressure (e.g., 15,000 to 30,000 psi).

Binder (Usually NOT Required): The immense pressure creates a mechanical interlock and breaks down oxidation layers, allowing for cold welding. For most metals, no binder is needed. Pure, dry briquettes are preferred by recyclers.

Advantages of Briquetting Any Metal Chip:

Reduced Volume: Up to a 10:1 reduction, slashing storage and transportation costs.

Value Recovery: Briquettes are a premium, commodity-grade product sold at "post-production scrap" prices, much higher than loose, oily chips.

Cleanliness & Safety: Eliminates pools of oil/coolant, reduces dust, and minimizes fire hazards (for most metals).

Improved Recycling: Mills and foundries pay more for briquettes because they melt more efficiently, with lower metal loss (oxidization) and better furnace feed control.

Conclusion

Yes, metal briquetting presses are versatile and can handle chips from almost any machined metal. The process is standard for ferrous metals, aluminum, and copper alloys. For exotic or pyrophoric metals like titanium and magnesium, it is still possible but requires a risk assessment and often a specialized, safety-focused press system.

If you are considering briquetting a specific metal type, it is best to consult directly with briquetting press manufacturers. They can provide test reports and machine recommendations based on your exact material mix and volume.
