In the B2B supply chain of international watches and clocks, many brand owners, independent sellers or cross-border e-commerce enterprises will face an extremely critical bottom choice at the beginning of the project: the case material should be 316L steel or zinc alloy.

In the professional watchmaking industry, the choice of case material not only directly determines your factory manufacturing process, technical threshold, but also at the moment of writing, the retail customer unit price of your brand, the user repurchase rate and the final brand fate.

Here, through pure material science and business logic, we present you with a hardcore explanation.

A, material hard to check than: 316 l stainless steel vs. zinc alloy

To understand the gap, you must first strip away the marketing rhetoric and go back to the underlying data of metallurgy and manufacturing.

1. Dimensional Impact of Physical and Chemical Properties

316L steel: belongs to low carbon austenitic stainless steel, due to the addition of molybdenum (Mo) element, so that it has a very high resistance to pitting corrosion and crevice corrosion ability. It is commonly used in surgical implants and high-end diving equipment. It is absolutely immune to chloride ion attack in human sweat, will never fade or flake, and has high allergy resistance.

Zinc alloy: essentially is zinc based on the addition of other elements of the alloy, its chemical stability is very poor, because zinc itself is easy to oxidize in the air, so zinc alloy case must rely on the surface of a layer of electroplating layer (usually nickel, chromium or copper) to maintain gloss. Once it comes into contact with human sweat for a long time, the plating will gradually erode and peel off, revealing the zinc alloy matrix with black and pitted interior, and even causing severe skin allergy to the wearer.

2. Huge Gap in Manufacturing Process (CNC Precision Machining VS Die Casting)

The birth of 316L stainless steel case requires industrial-grade CNC machines for multiple processes of precise cutting and cold forging. Every geometric line, every border between drawing and polishing, requires a micron level of craftsmanship.

Zinc alloy case is a typical liquid metal gravity die casting or injection molding, due to the low melting point (about 400℃), the factory speed is very fast, but the internal easy to produce pores and sand holes. As a result, the zinc-alloy watch case cannot withstand the hydrostatic test at a vacuum depth of more than 5ATM, and is prone to structural fracture when worn for a long time or accidentally dropped.

B. brand premium strategy: How does the material determine your profit space?

In the world of B2B watch customization, many unsophisticated buyers often make a mistake: they choose zinc alloy in order to save a few dollars on the factory price, but do not know that this directly cuts off the brand's premium space of dozens of times in the front-end market.

"Multiplication Effect" of Cost and Selling Price

In the retail market of watches, especially for mainstream overseas consumer groups such as Europe, the United States and the Middle East, the authenticity of materials is the first step to establish trust. The difference in raw material costs of a few dollars may generate several times the profit return gap in the terminal retail market after being amplified by brand marketing. Of course, the price customization of different products directly determines the profit of the product. Whether it is popular or high-end bargaining depends on your watch brand positioning.

C.modern B2B purchase selection guide: how to brand vision precise layout?

Do you want to be in order to help the high quality brand of high quality B end customer clear logic, we in the research and development phase of project, material layout Suggestions follow the following principles:

1. Match the case material according to core technology processes

If your watch design contains complex surface scale processing, three-dimensional hydraulic literal texture, or the need for advanced wire drawing with mirror polishing staggered color matching process, then you have to use 316 l stainless steel. Due to the soft material and many internal pores, zinc alloy cannot withstand the high-precision wire drawing process at all, and the surface made will only have a flashy plastic cheap feeling.
