High-temperature solder bars are enhanced with specially formulated additives in tin-lead alloys, enabling their oxidation function at temperatures above 450°C. These products are suitable for welding processes with high working temperature requirements, such as soldering transformer lead wires. Our factory offers a variety of alloy ratios for customer selection.
Chinese Name: Lead-Free Solder Bar English Name: Lead-Free Solder Bar Tin Content: Sn99.3/Cu0.7 Melting Point of Solder Bar: 227℃ Operating Temperature: 280℃-350℃ Solder Bar Per Carton: 20kg (Please leave a message to inquire about stock availability) Han Dao Company produces lead-free solder bars using high-purity electrolytic tin from Yunnan and copper as raw materials.
Solder wire is an essential component in the production and maintenance of the electronics industry. There is a wide variety of solder wire available, with different qualities and prices. Common types include tin-lead alloy solder wire, antimony alloy solder wire, bismuth alloy solder wire, silver alloy solder wire, copper alloy solder wire, and more. Solder wire is widely used in various modern electronic assembly and welding applications. It is made by mixing electrolytic pure tin and lead with high-grade metal antioxidant alloys, and then melted, refined, and decontaminated in a high-temperature furnace. It is then cast or molded into shape using an oil-pressure machine.
Electrolytic solder wire introduction:
The Han Island solder production electrolytic solder rods are made from high purity metals, under strict quality control conditions in a dual-metal electrolytic workshop, after vacuum deoxygenation treatment, effectively controlling the degree of oxidation and the content of new metals and non-metals. The raw materials used in the electrolytic solder rods have undergone rigorous multi-level electrolytic purification processes and special melting refining procedures, greatly removing fine oxide inclusions from the solder, and adding trace antioxidant elements to the electrolytic solder rods. The operating temperature is below 300°C, with the solder liquid surface as bright as a mirror, ensuring the quality of the solder products and minimizing oxidation residue. The high-antioxidant electrolytic solder rods have the following advantages:
Pure tin and copper, high-grade anti-oxidation alloy. Excellent wettability, no cold solder joints. Good anti-oxidation properties, minimal slag, cost-saving. Extremely low levels of harmful impurities, enhancing diffusion and flowability. Stable performance, suitable for wave soldering or hand dipping furnace welding.
Company Introduction
Wuhan Hando Technology Co., Ltd. is committed to the research, development, and sales of electronic materials such as solder wire, solder bar, and solder paste, along with waste solder recycling services. With the rapid development of the electronics information industry in the central and western region, there is an increasing demand for high-quality solder electronic materials. To better serve customers in the central and western region, with support from Huangpi District and Zhuoer Holding, Wuhan Hando Technology Co., Ltd. was established in the Panlongcheng Economic and Technological Development Zone, Huangpi District.
High-temperature solder bars are those that can maintain non-oxidation at working temperatures exceeding 450℃ and are capable of normal welding, with a liquidus temperature higher than the tin-lead eutectic melting point (183℃).
