Material Spotlight: Brass. Why its golden glow resonates with your life.
Brass is used in many CTSH products. Why do we love this material so much and make it the centerpiece of our machining process? This time, we explore the overwhelming appeal of brass that stimulates the five senses.
A "Substantial Density" That Comes Alive Through Machining
Brass is an alloy of copper and zinc. The "substantial weight" you feel the moment you pick it up is proof of the material's high density. We machine shapes from these brass ingots without compromise. The "genuine sense of mass" that can never be achieved with hollow pressed parts or surface plating alone brings a distinct elegance to any space.
A "Golden Luster" That Warms the Space
The greatest appeal of brass is its uniquely alluring glow. Not as flashy as gold, yet more refined than copper, it has a nostalgic, warm yellow hue. When this color reflects the light from a bulb, it seems as though the light itself has acquired warmth, softly enveloping the entire space.

The Beauty of Aging That Evolves With You
Brass changes slowly and dramatically as it comes into contact with air and human hands.

Enjoy the Transformation: From a vivid golden color to a deep antique brown, and eventually to a dark, subdued patina. It is not merely "deterioration," but a record of the time spent with you. Every day you touch the switch and look up at the light. This accumulation nurtures a one-of-a-kind "color of yours" in the world.
Key Point!

A Timeless Glow That Can Be Restored by Polishing: The wonderful thing about brass is that even after you have enjoyed its patina, it can be polished to regain its original luster. The reason it is said to be "for a lifetime" lies in this resilient beauty that can be renewed time and time again.
Experience the Pulse of Metal With All Your Senses
The sharp edges of the machined form, the weight unique to brass, and the color that deepens with the passing years. Brass is not just a "material." It is a "living material" that stays close to the user's lifestyle and grows together with them. The reason CTSH continues to focus on brass is that we want to bring an unchanging sense of security and the joy of constant change to your everyday life.
