K&S 1-1/16in Brass Round Tube, .029in Wall (36in long)

Since 1946, K&S Precision Metals has been the industry standard for high-quality, small-diameter metal products. Based in Chicago, Illinois, this family-run American manufacturer provides an extensive range of precision-engineered metals designed for hobbyists, engineers, architects, and makers. Known for their tight tolerances and world-class telescopic tubing, K&S products are the essential choice for projects requiring exact fits and professional-grade finishes.

Key Material Types:

• Brass (Alloy 260/272): The flagship of the K&S line. Highly versatile, easy to solder, and available in round, square, rectangular, and hexagonal shapes.
• Aluminum (6061-T6 / 3003): Lightweight and corrosion-resistant. Ideal for weight-sensitive projects like RC aircraft or architectural framing.
• Copper (Alloy 122/110): Excellent for electrical conductivity and heat dissipation. Often used for custom plumbing in scale models or decorative arts.
• Stainless Steel (304/304L): Offers superior strength and high resistance to oxidation. Perfect for structural components that require a polished, "industrial" look.
• Music Wire: High-carbon spring steel designed for tension and structural rigidity, common in RC linkages and spring fabrication.

Why Choose K&S?

• Unrivaled Tolerances: Most tubing is held to a strict ± .002" tolerance, ensuring that different sizes "nest" perfectly inside one another for telescopic use.
• USA Manufactured: Proudly made in America, ensuring consistent material quality and ethical production standards.
• Global Compliance: All materials are fully REACH, RoHS, and Prop 65 compliant, making them safe for consumer products and international export.
• Hobbyist Friendly: Sold in convenient lengths (typically 12" or 36") that are easy to ship and store, minimizing waste for small-scale projects.

Maker’s Tip:

To achieve a professional "factory" finish on K&S metals, use a fine-grit sandpaper (400-600 grit) to remove the mill finish, followed by a metal polish like Brasso or Simichrome. If you are soldering K&S brass or copper, ensure you use a rosin-core solder or a dedicated liquid flux to guarantee a bond that is as strong as the metal itself.
