Types of black oxide
Based on the operating temperature and the chemical solvent used, black oxide is generally divided into the following types: Hot black oxide The hot black oxide process operates at 140℃- 155℃. Immerse the metal workpiece in strong alkaline solutions such as NaOH and NaNO₂ to form a deep black and wear-resistant film on its […]
What is black oxide?
Black oxide, which is also called blackening, is a type of chemical conversion coating process mainly applied to ferrous materials like steel or iron. The metal reacts chemically with a specific alkaline oxidising solution to produce an extremely thin layer of iron oxide(Fe₃O₄) film. This film(about 0.5-1.5μm)is uniformly black and tightly bonded to the metal […]
The Aluminum Alloy Series
The Aluminum Alloy Series (4-Digit System) 1xxx Series: Pure Aluminum (99.0% Minimum Aluminum) Major Alloying Element: None (Pure Aluminum). The last two digits indicate the purity above 99.00%. For example, 1060 is 99.60% aluminum. Characteristics: Excellent corrosion resistance. High electrical and thermal conductivity. Excellent workability (easy to form and weld). Low mechanical strength. Not heat-treatable; strength […]
Benefits of aluminum laser engraving
Permanent and durable Laser engraving creates marks by melting or vaporizing the designated area of aluminum, rather than simply printing on the material surface. Therefore, the engraved mark is durable and indelible. Even if the aluminum is subsequently subjected to surface treatment such as anodizing, the mark remains permanent and wear-resistant. High precision […]
Components and Parts Aluminum is Commonly Used
Aluminum is one of the most versatile and widely used engineering materials due to its exceptional properties: it’s lightweight (about one-third the density of steel), corrosion-resistant (forms a protective oxide layer), highly malleable and ductile, a good conductor of heat and electricity, non-magnetic, and non-toxic. It’s also easily recyclable without loss of quality. These properties make it suitable for producing a vast array of components across […]
What is laser engraving?
As a subtractive surface treatment method, laser engraving forms patterns or text by making use of a laser beam to remove or alter the material’s surface. Advantages of engraving High precision Take the most used fiber laser engraving machine for example, it can engrave a thin line of 0.01mm(about 1/5 of human hair) at […]
Types of laser engraving machines for aluminum
According to the different media that generate lasers and the laser wavelengths, there are many types of aluminum laser engraving machines. Choosing the correct type of laser is crucial for the effect of aluminum engraving. Fiber laser Fiber laser has a wavelength of 1064nm, which can reach an absorption rate of about 4–10% by […]
Key Elements of a Process Flow Chart
A process flow chart (or flowchart) is a visual representation of the steps, sequences, and decisions involved in a process. Its core purpose is to communicate how a process works clearly and concisely to all stakeholders. The essential elements can be broken down into two main categories: Symbols (Shapes) and Connecting Elements & Best Practices. Core Symbols (The […]
Process Control in Hot Forging
Hot forging is a complex metal forming process where metal is shaped at high temperatures (typically above the recrystallization temperature). Precise control over every step of the流程 (process flow) is critical to achieving parts with the desired mechanical properties, dimensional accuracy, and microstructure, while minimizing defects and production costs. The control strategy can be broken […]
Aluminum surface finishing and laser engraving effects
The laser engraving effect on aluminum material does not depend on the type of substrate, but rather on its surface finishing condition. Here are three kinds of aluminum with different surface treatments that are commonly used for laser engraving: Anodized aluminum Based on the anodizing process, the thickness of the anodized layer typically ranges […]
