Brass and copper are two popular metal alloys in industry and handicrafts. However, not everyone can distinguish between these two materials. The following article from Oristar - a pioneer in providing high-quality non-ferrous metals - will help you identify and distinguish between brass and copper easily and accurately.

Metal heat treatment is a critical process that directly determines the hardness, durability, and overall lifespan of metal products. In industries such as precision engineering, mold manufacturing, automotive components, aerospace, and industrial equipment, properly controlled heat treatment plays a decisive role in ensuring product performance and reliability. So, how exactly does heat treatment influence hardness and service life? Let’s explore the technical aspects in detail.

In precision engineering, selecting the right material directly impacts strength, dimensional stability, and machining costs. Among aluminum alloys, 6061 and 7075 are two of the most widely used grades — each suited for different applications.

Trump's tariffs, US-China trade relations, and a wave of AI investment are among the issues that could shape the global economy in 2026.

In recent days, storm No. 13 has caused heavy damage to the provinces of Gia Lai, Dak Lak and Quang Ngai, greatly affecting the lives of many households, especially students in difficult circumstances.

Oristar is proud to be featured in an interview with Japan Metal Bulletin – one of the most prestigious daily newspapers in the non-ferrous metal industry in Japan.

In the mechanical and metalworking industry, choosing the right grade of aluminum (aluminum alloy) for each application is a decisive factor in performance, durability and production costs. However, in many cases, some aluminum product codes can be interchangeable while still ensuring technical requirements and product quality.

The US President said the trade deal with China was complete for him and President Xi Jinping to approve.

Months after announcing plans to impose a 100% tariff on semiconductors, the US is being more cautious to avoid a rift with China.

In the field of metalworking, aluminum is a popular material due to its light weight, high corrosion resistance and easy to shape. The two most popular aluminum grades are A5052 and A6061. Although there are many similarities, in many practical applications, A6061 can completely replace A5052 - especially in products that require better hardness, strength and machinability.

The two major exhibitions of the year – FBC in Hanoi and METALEX in Ho Chi Minh City – have ended with many memorable moments.

At Oristar, we provide genuine, high-quality A6061 aluminum, ensuring to meet all strict technical standards of domestic and foreign customers.
