This article introduces BASE METAL , which is used in many DIARGE items.

Base metals are metals that have large reserves and production volumes and are easy to refine. It refers to iron, copper, zinc, tin, aluminum, etc.

In Japanese, the word " base metal " , which is the antonym of precious metal, applies.

Base metals are somewhat complicated as there are chemical classifications and trade classifications.

According to Wikipedia , the explanation is as follows.


chemical classification

Metals with a higher ionization tendency than hydrogen (= less stable ) , metals that are easily oxidized in air.

By the way, the word "base metal" is derived from calling a metal with a high ionization tendency " base metal " , and does not mean "base metal " ( antonym: noble ) .

Trade classification

Steel, copper, aluminum, lead, zinc, tin, tungsten, indium, molybdenum, chromium, germanium, tantalum, magnesium, cobalt, cadmium, titanium, zirconium, vanadium, gallium, antimony, manganese, nickel, beryllium, hafnium, niobium, Bismuth, rhenium, and thallium are base metals.

At DIARGE, we prefer to use the term base metal instead of the Japanese word for base metal. The reason is that the image associated with the sound of the words is good.

Don't you get the impression that metal supports the BASE of society and our lifestyles? There is a canned coffee commercial slogan that says, "The world comes from someone's work," but I think base metal is about someone who doesn't have a name.


DIARGE mainly uses brass and stainless steel among the base metals. Brass, also known as brass, is an alloy of copper and zinc, especially those containing more than 20% zinc. Stainless steel, which is called stainless steel in English, is an alloy containing iron as the main component (more than 50% ) and chromium and nickel. Although they differ in color, hardness, and properties, they are all highly ductile and tough alloys, are easy to work with, and are easy to distribute.

DIARGE 's base metal items are mobile accessories, stationery, and interior accessories for men that require strength and practicality, and are planned with the intention of enjoying the original texture of metal. Alloy is used as the main material.

The original color of brass is a whitish gold color, but as the main component copper is oxidized, it changes to a slightly blackish color. For example, the expression antique style is a change that fits nicely. It is a metal that can best be enjoyed over time as seen in natural wood, leather and denim.

Stainless steel, on the other hand, has a silvery color that accounts for the majority of metals, and has the characteristic of maintaining the color and texture of the stage at which it was born, as the etymology suggests.

If you're looking for a deep taste depending on the age and usage conditions, brass is for you, and if you're looking for a minimalist texture, stainless steel.

 With DIARGE products, we aim to bring out the depth of the texture and usefulness of the product by making full use of a wide variety of processing techniques, with the aim of allowing people to enjoy the original texture of metal.

I hope that it will be the one and only product for someone's lifestyle.
