AMPCO K-21 Scraper – Stiff – 1-1/4″ – Nickel Copper Alloy

The AMPCO K-21 Scraper is a precision-engineered, non-sparking hand tool designed for controlled material removal in hazardous and high-risk environments. Built from proprietary nickel aluminum bronze alloy, this scraper delivers the strength of hardened steel with the safety profile required in explosive atmospheres.

This is not a general-purpose consumer scraper.
This is controlled-force industrial equipment.

Engineered for Hazardous Work Zones

The K-21 is manufactured from AMPCO’s nickel copper alloy, a material specifically developed for:

• Non-sparking performance in flammable environments

• Corrosion resistance in marine and chemical conditions

• Non-magnetic properties for sensitive applications

• Long-term durability under repeated industrial load

When working in refineries, fuel storage facilities, grain processing plants, mining operations, or explosive manufacturing zones, standard steel tools introduce ignition risk. The K-21 eliminates that variable.

Tool Specifications

• Blade Width: 1-1/4″

• Blade Type: Stiff

• Material: Nickel Aluminum Bronze (AMPCO Alloy)

• Spark Resistant

• Corrosion Resistant

• Non-Magnetic

• Industrial-Grade Construction

The stiff blade configuration allows for controlled scraping of gaskets, sealants, corrosion buildup, coatings, and bonded material without flex distortion.

Built for Real-World Industrial Abuse

Unlike plated tools that wear down to expose unsafe substrates, this scraper is solid alloy throughout. Performance does not degrade when surface coating wears — because the safety properties are inherent in the metal itself.

This makes it suitable for:

• Petrochemical plants

• Oil & gas service work

• Aerospace maintenance

• Marine operations

• Defense applications

• Explosive atmospheres (ATEX-style environments)

• Confined space maintenance

Why Nickel Aluminum Bronze Matters

Nickel aluminum bronze alloys provide:

• High tensile strength

• Excellent galling resistance

• Superior wear resistance compared to brass

• Stable dimensional integrity under heat

In environments where static discharge, friction sparks, or tool impact can cause catastrophic ignition, this alloy becomes a liability reducer.

Controlled Removal. Reduced Risk.

The 1-1/4″ blade width offers a balance between precision and leverage, allowing technicians to remove material cleanly without over-torquing or damaging adjacent surfaces.

This is not decorative hardware.
This is compliance-grade tooling.
