Brass conducts electricity well and has a warm metallic look, so it suits conductive or premium products; stainless steel is stronger and more corrosion-resistant. Upsilon makes both in the same sizes and precision, so the choice comes down to look and conductivity versus strength.

Yes. Bare brass darkens as it reacts with air, so most customers choose chrome or nickel plating, which prevents tarnish and keeps the look lasting. If you want the natural brass color, choose polishing and expect the color to mellow over time.

Both add a thin metal layer over the brass to prevent tarnish and keep the finish lasting. Chrome is cooler, brighter and harder, so it resists scratches better; nickel is warmer with a softer sheen. Upsilon can recommend one to match your brand.

Yes. Chrome and nickel are metals too, and the plating is thin, so conductivity is essentially unaffected. Many of the pull-out antennas on classic radios and TVs were chrome-plated brass telescoping tubes.

Yes. Upsilon brass tubing shares the stainless diameter range, the 25 stock sizes, wall thicknesses and the ±0.05 mm tolerance, and can be slotted in the same way.

Yes. Antennas are where Upsilon started. The pull-out antennas on classic radios and TVs were often chrome-plated brass telescoping tubes: brass conducts well and the plating prevents tarnish. Send us the length, number of sections and end-fitting requirements, and we will match the diameters and telescoping structure.

We can evaluate it. Upsilon’s 25 brass stock sizes go straight to production; any other size within Ø2.8–23 mm and a 0.2–0.4 mm wall can be evaluated for your project.
