Nuestra variedad de pinzas cumple con una multitud de aplicaciones en la ciencia, la investigación y la industria. Observe las pinzas DUMONT® de alta calidad incrementadas en estilos y números.
A continuación se muestra una lista que describe los metales y los códigos utilizados para distinguirlos.
Los grupos de pinzas representativos se enumeran arriba para un enlace rápido a los tipos específicos.
Las medidas de los puntos de las pinzas deben tenerse en cuenta para su aplicación. Por ejemplo, el punto más afilado y pequeño (nuevo en este catálogo y en nuestra web) es el número 505-U, que es de acero inoxidable con puntas de tamaño 0,025 x 0,005 mm. Esta es una pinza especial adecuada, por ejemplo, para recoger rejillas EM de superficies muy lisas. La mayoría de las aplicaciones no requieren una pinza tan fina y sus opciones son múltiples.
Las pinzas Dumont Dumostar ™ son las pinzas más duras. Son no magnéticos con acero resistente a la corrosión (agua de mar, HCl, H3PO4, HNO3, H2SO4). Son resistentes a ambientes neutros y alcalinos. DUMOSTAR ™ de DUMONT es superior al mejor acero inoxidable. La dureza de la punta es progresiva y alcanza su punto máximo en la zona de una pinza estilo 5 con una dureza de la punta en el rango de Rockwell de 63-64.
Incluso las aleaciones de acero no magnéticas pueden exhibir magnetismo cuando se exponen a fuertes campos magnéticos. Solo las pinzas de titanio o plástico son completamente no magnéticas.
Abreviaturas de metales y materiales:
Aleaciones y materiales
Una mezcla de aleación de acero, cromo, níquel y cobalto, de naturaleza elástica para “puntas flexibles resistentes a la fatiga”, resiste temperaturas de hasta 550 ° C, no es magnética y es anticorrosiva. El mejor material en general para pinzas. Rockwell 63-64.
La aleación de acero al carbono / cromo de alta resistencia a la tracción (varias composiciones) proporciona una buena resistencia a la corrosión y las manchas, superada únicamente por DUMOSTAR ™ en dureza. Nota: el acero inoxidable se puede oxidar en algunas circunstancias.
NM-SS Acero inoxidable no magnético
Las mismas propiedades del acero inoxidable con níquel adicional para crear la característica no magnética.
Aleación estándar compuesta por C, Cr, Ni y Mo. Ofrece una buena resistencia a la corrosión gracias a su alta concentración de Mo y es 80% no magnética, pero no es tan dura como el acero inoxidable NM. NM es resistente hasta temperaturas de alrededor de 400 ° C (DIN 50 914) y es adecuado para esterilización en autoclave a 270 ° C.
Puntas flexibles, no magnéticas, livianas (33% menos que las aleaciones de acero inoxidable), duraderas, con baja desprendimiento de partículas en comparación con el acero inoxidable, extremadamente ácido y resistente a las manchas, hipoalergénico. Bueno para usar alrededor de componentes electrónicos sensibles o campos magnéticos altos. Resiste temperaturas superiores a 400 ° C. Rockwell 36.
Material muy duradero y duro que es menos flexible y más quebradizo que DS, SS y Ti. Altamente magnético, se mancha y se oxida fácilmente. Rockwell 60.
Altamente resistente a la corrosión y proporciona puntas suaves y flexibles. Más resistente a las manchas que el acero inoxidable, dureza Rockwell 63. 95% antimagnético, resistente a temperaturas superiores a 400 ° C. Puede esterilizarse en autoclave.
Compuesto por una mezcla especial de acero al carbono y cromo. Proporciona puntas suaves y flexibles, Rockwell 55.
